Abstract: An antenna system for an airborne radar system. The antenna system has a number of first antenna elements and a microwave power distribution system comprising a plurality of first T/R-units being coupled to the first antenna elements for distribution of microwave power to the plurality of first antenna elements. The microwave power distribution system has an assembly of waveguides coupled to a plurality of second antenna elements directed at an angle essentially perpendicular to the number of first antenna elements, wherein the first T/R units are coupled to the waveguides for distribution of microwave energy to the second antenna elements.

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

Abstract: 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.
