摘要： The invention discloses an antenna (100, 100′, 400, 500) comprising walls in a conducting material: first (110, 410, 510) and second (120, 420, 520) main walls, a first end wall (130, 530) and a first and a second side wall. The first (110, 510) and second (120, 520) main walls extend in parallel to each other, and are joined by the first end wall (130, 530). The side walls also join the first and second main walls, so that a cavity with only one opening (105, 205, 505) is formed, a rectangular aperture which can be brought to radiate by a feed connection (207). Suitably, the antenna can also comprise a second end wall (140, 540) which extends from the second main wall (120) towards the first main wall (110), with the length of extension of the first main wall being such that the second end wall and the first main wall do not meet.

摘要： A self-complementary patch antenna is disclosed. A hexagonal lattice (10) consisting of triangular conducting patches (1) is formed together with at least one dielectric layer onto a ground-plane. Each triangular patch is then fed by means of three RF signal probes in a symmetrical configuration positioned near each corner of the triangle, whereby an arbitrary lobe-steering and polarization state can be established by selection of amplitude and phase for each RF signal probe.

摘要： The invention provides an improved array antenna, an array antenna system and an improved method for utilizing the improved array antenna and array antenna system. This is accomplished by an array antenna comprising a region of reference potential, e.g. a ground plane, and a spatially extended collection of at least two antenna elements capable of being at least partly balanced driven and at least partly unbalanced driven. The antenna elements have a first radiating element connected to a first port and a second radiating element connected to a second port. In other words, the antenna element has at least two ports. The radiating elements are arranged substantially adjacent and parallel to each other so as to extend at least a first distance approximately perpendicularly from said region of reference potential. The antenna element is further comprising a radiating arrangement connected to said first and said second radiating elements so as to extend at least a second distance above and approximately parallel to said region of ground reference.

摘要： The present invention relates to a broadband non-resonant antenna device for wireless transmission of information using electromagnetic signals, comprising a metal sheet layer, forming a plane, with a slotline that comprises a first part and a second part. The side of the second part that is the most distant from the first part transcends into a widening open-ended tapered slot in the metal sheet layer. The device additionally comprises a feeding line in the metal sheet layer. The feeding line comprises a feeding part, with a first end and a second end, and gaps separating the feeding part from the surrounding metal sheet layer by a certain distance, where the slotline is intersected by the feeding line.

摘要： A dual polarised wave-guide notch antenna array is disclosed. The device comprises a feed section (1) having at least two input transmission lines, a feed/wave-guide interface (5) providing an aperture for transferring a radio frequency electromagnetic wave between the feed section (1) and a wave-guide mode in a wave-guide section (3) having ridges. The wave-guide section transfers energy between the feed/wave-guide interface and a tapered notch section (7), thereby gradually adjusting a created electromagnetic field towards free space conditions.
