The microwave device comprises two conducting layers arranged with a gap there between, and a set of periodically or quasi-periodically arranged protruding elements fixedly connected to at least one of said conducting layers, thereby forming a texture to stop wave propagation in a frequency band of operation in other directions than along intended wave guiding paths, thus forming a so-called gap waveguide. All protruding elements are connected electrically to each other at their bases at least via the conductive layer on which they are fixedly connected, and some or all of the protruding elements are in conductive or non-conductive contact also with the other conducting layer.A corresponding manufacturing method is also disclosed.

A microwave/millimeter device having a narrow gap between two parallel surfaces of conducting material by using a texture or multilayer structure on one of the surfaces is disclosed. The fields are mainly present inside the gap, and not in the texture or layer structure itself, so the losses are small. The microwave/millimeter wave device further includes one or more conducting elements, such as a metallized ridge or a groove in one of the two surfaces, or a metal strip located in a multilayer structure between the two surfaces. The waves propagate along the conducting elements. At least one of the surfaces is provided with means to prohibit the waves from propagating in other directions between them than along the ridge, groove or strip. At very high frequency, the gap waveguides and gap lines may be realized inside an IC package or inside the chip itself.

A quasi-planar array antenna for transmitting or receiving electromagnetic waves is disclosed. The antenna comprises elements being in the form of slots that extends in H-plane from one side of the array to the other and being limited at both ends by sidewalls, and being located side-by-side to form a planar radiating aperture. The slots are fed in such a way that one or more directive beams are radiating vertically or almost vertically from said planar radiating aperture. A feeding arrangement and/or power distribution arrangement may be realized by means of parallel-plate-type waveguides, and preferably incorporating gapwave technology.

The present invention relates to a self-grounded antenna arrangement (10) comprising a base or central portion (5) arranged in a first plane and a number of arm sections (1,2,3,4) associated with said central portion (5), which taper towards a respective end tip. It comprises an electric conducting material, each arm section being adapted to form a transition from the central portion and being bent backwards towards the central portion by more than 180° so that its end tip approaches a first side of the central portion, at an opening therein. The end tip is connected to feeding means for feeding via an arm section specific port, one specific port ( 111, 112,113; 114;) for each arm section. Each arm section (1,2,3,4) comprises a mixed functionality of a curved monopole antenna and a loop antenna, and the antenna arrangement provides substantially uncoupled ports with far field functions that are almost orthogonal in polarization, direction or shape. The invention is in particular intended for use in MIMO antenna systems for statistical multipath environments.

Conventional machining such as, but not limited to: drilling, milling and sawing, cannot define the structures with the precision required of devices between 100 GHz and 10 THz. To obtain the high precision required, microsystem manufacturing methods such as deep reactive etching can be used to define the structures with high precision. Alternative fabrication methods such as injection molding or other micromolding process may also be used. A metal layer can cover some or all surfaces.

The present invention represents a new, way of packaging passive and active microwave circuits, and in particular circuits involving microstrip transmission lines and similar substrate bound transmission lines. The circuits are located between two conducting surfaces, one of these surface may be the ground plane of the microwave circuit, and at least one of these surfaces are provided with conducting elements formed as angular or curved conducting lines arranged on substrates. The conducting lines may e.g. have a zigzag shape. The two surfaces may form the bottom and lid of a cavity with conducting sidewalls. The conducting elements may with advantage be arrange in a periodic grid, and create together with the ground plane of the microwave circuit board or the smooth metal plane below the microwave circuit board a stop band for waves propagating between the lid with conducting elements and the ground plane. Thereby, cavity resonances are avoided or suppressed that otherwise create a big problem associated with the packaging in metal boxes with smooth metal walls.
An improved eleven antenna is disclosed, comprising a conducting body acting as a ground plane; and at least one pair of log-periodic dipole arrays arranged above the ground plane, the dipoles of said pair of log-periodic arrays of dipoles forming dipole pairs of parallel and oppositely located dipoles of the same dimensions and arranged in such a way that the geometrical centres of each of said dipole pairs and their images in the ground plane are coinciding,wherein each dipole is a folded dipole comprising two or more parallel or nearly parallel conducting strips that are connected at one or more points or over an extended part of the conducting strips. Further, a plurality of the folded dipoles, within each of said log-periodic dipole array, being closer to said geometrical centre are extending in a first plane, and wherein the remaining at least one folded dipole being located most far away from said geometrical centre is arranged to extend in at least one additional plane, said additional plane(s) forming an angle relative to said first plane. Hereby,a more compact antenna is achieved.

The invention describes a broadband multi-dipole antenna that has low input reflection coefficient, low cross polarization, rotationally symmetric beam and constant beam width and phase center location over several octaves bandwidth. The dipoles are fed from one or a few feed points, and they may with advantage have log-periodic dimensions. The antenna is more compact, has lighter weight and is cheaper to manufacture than other solutions. It is very well suited for feeding single, dual or multi-reflector antennas.
