The present invention relates to a communication device, a dielectric waveguide filter and a capacitive coupling adjustment method thereof. The dielectric waveguide filter comprises a dielectric block and a metal layer. During a production and design process, a capacitive coupling amount can be correspondingly adjusted by adjusting the size of a groove opening of a blind groove or by adjusting the depth of the blind groove, and the adjustment of the capacitive coupling amount does not require the adjustment of the size of a partition ring, that is, the capacitive coupling amount is no longer limited by the impact of the machining precision of the partition ring, therefore, the machining difficulty can be reduced, production and manufacturing are facilitated, debugging is facilitated, and batch production can be achieved. Furthermore, the partition ring only plays a role in capacitive coupling and is not used for adjusting the capacitive coupling amount; and when designing a partition ring, a partition ring with a relatively small size can be used, without needing to increase the size of the partition ring, and therefore, leakage of a large number of signals and serious signal crosstalk caused by a large opening at the partition ring can be avoided, such that the effect of there only being a small amount of signal leakage at the partition ring can be realized, and mutual interference between dielectric waveguide filters is greatly reduced.

In addition, the first blind hole can also be used for adjusting a capacitive coupling amount; and the deeper the first blind hole, the greater the capacitive coupling amount, such that the filter is designed more flexibly.

The hardware costs of an access network device can be reduced by adopting the present method.
The present invention relates to a filter and a dielectric resonator thereof, the dielectric resonator comprising a dielectric block and a metal layer coating the external surface of the dielectric block. The dielectric resonator has a first surface and a second surface arranged to oppose each other, wherein a metalized blind hole is formed on the first surface for a PIN of a radio frequency connector to insert, and a recessed structure different from the metalized blind hole is also formed on the first surface. The forming of the recessed structure on the first surface of the dielectric resonator can have the effect of strengthening the coupling between the RF connector and the dielectric resonator, thereby achieving bandwidth regulation at input and output ends and changing time delay. When the dimension of the recessed structure is increased, the time delay at corresponding input and output ends increases. Therefore, while increasing the depth of the metalized blind hole, the dimension of the recessed structure can be adjusted to make the time delay to meet requirements. When the depth of the metalized blind hole increases, the insertion length of the PIN also increases, and thus the welding strength of the PIN is higher, such that the reliability of the above filter is significantly improved.

In addition, each shielding cavity shields dielectric filter modules accommodated therein, such that the multiple dielectric filter modules used in combination with the shielding cavity can be viewed as functionally equivalent to multiple conventional dielectric filters. Moreover, since each shielding cavity accommodates at least two dielectric filter modules, the number of the shielding cavities may be far less than the number of the dielectric filter modules. Compared with conventional configurations in which dielectric filters are directly mounted, the invention allows elimination of a large number of metal shielding cavities, and the array antenna can thus have a lightweight design.

When a capacitive coupling bandwidth of the capacitive coupling structure of a dielectric filter needs to be adjusted, the spacing H1 between the bottom wall of a first blind hole and a second surface is adjusted accordingly, specifically, for example, when producing and manufacturing a narrow-frequency band dielectric filter, the capacitive coupling bandwidth is reduced by increasing the spacing H1 between the bottom wall of the first blind hole and the second surface, and a large enough spacing H1 can be selected to process the narrow-frequency band dielectric filter, thus facilitating the production and processing, and having a high production efficiency; in addition, the hole wall of a tapered hole section is arranged obliquely relative to a first surface, thus making it convenient to form the metal layer on the hole wall of the first blind hole, and facilitating performing a processing operation on the metal layer of the tapered hole section by using a cutting tool (including a cutter, a laser, etc.), thereby improving the production efficiency.
The present application provides an antenna and a radiation unit thereof, and a balun structure of a radiation unit. The radiation unit has two dipoles belonging to the same polarization and two feed components feeding the two dipoles respectively; each of the two feed components has one end electrically connected to the corresponding dipole, and the other end implements combination by means of the same inherent physical combination port of the radiation unit. By providing an inherent combination port of the radiation unit, and connecting same to one end of each of two feed components (e.g. a coaxial cable) connected to two dipoles of the same polarization, signals of the two dipoles can be split/combined by means of the combination port, so that when the radiation unit is applied to an antenna, by using only one coaxial cable to connect the radiation unit between the phase shifter and the combination port, a phase shifter can feed two dipoles of the same polarization, reducing the number of coaxial cables on the back side of a reflection plate, simplifying the layout of the back side of a reflection plate.
The present application provides a base station antenna and a radiating element thereof. The radiating element comprises a dipole, a balun supporting the dipole, and a feed component feeding power to the dipole. The balun comprises a pair of balun arms disposed opposite each other, and at least one of the balun arms is configured to be hollow. The feed component comprises a feed conductor and an insulating dielectric. The feed conductor passes through the hollow balun arm and is connected to a radiating arm supported by the other balun arm. The insulating dielectric is fillingly disposed between the feed conductor and an inner wall of the balun arm, and securely fixes the feed conductor within the balun arm. The invention arranges the feed component composed by the feed conductor and the insulating dielectric in an internal cavity of the hollow balun arm, and the feed component and the balun arm compose a structure similar to that of a coaxial cable, thereby eliminating the need for a power feeding coaxial cable or a welding operation, saving on time needed for welding and alleviating electrical performance instability caused by welding. In addition, the invention does not use a coaxial cable, thereby reducing costs.
The present invention relates to a filter and a filter loop structure thereof. By means of providing a coupling branch, two coupling loops can be formed in a main loop. Moreover, since each coupling loop includes a capacitive coupling structure, a phase difference is generated in each coupling loop, such that a pair of zero points can be generated in each coupling loop. Therefore, compared with traditional filters, the filter has a pair of new zero points, and is of a six-cavity four-zero-point structure. Moreover, there is no need to change an arranged cavity structure of a filter loop, and a coupling branch only needs to be added, and the capacitive coupling structure only needs to be provided at a suitable position. In addition, a first resonator and a tail resonator in a main loop are provided on the same side, thereby facilitating the arrangement of input and output ports and being beneficial to saving on layout space of the filter. Therefore, the filter and the filter loop structure thereof have a simpler structure while achieving multiple zero points.
Disclosed are a duplexer, and a dielectric filter and a capacitive coupling structure thereof. The capacitive coupling structure comprises a first adjustment slot disposed between two adjacent dielectric resonators in a dielectric body and arranged according to a first preset length and a preset depth. One end of the first adjustment slot is spaced apart from a sidewall of the dielectric body, and the other end of the first adjustment slot is communicated with another sidewall of the dielectric body or the other end of the first adjustment slot is communicated with an isolation window. The capacitive coupling structure is easy to produce, and subsequent production debugging is facilitated. Thus, the dielectric filter using the capacitive coupling structure is easy to produce, and it is easy to perform production debugging. Thus, the duplexer using the dielectric filter has low production difficulty, and it is easy to perform production debugging.
