Abstract
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.

13. A dual polarised wave-guide notch microwave antenna array, comprising:
-
a feed section with at least two input transmission lines each connecting to a pair of feed elements;
a passive microwave circuit that creates necessary amplitudes and phases for desired polarisation states, wherein the feed section provides crossed slots or probes for transferring at least one wave signal into a wave-guide mode; and
,a feed/wave-guide interface with a general aperture shape allowing energy transfer between the feed section and a wave-guide section, wherein the wave-guide section has ridges and transfers energy between the feed/wave-guide interface and a tapered notch section, wherein the tapered notch section gradually adjusts a ridged wave-guide electromagnetic field mode towards free-space conditions. - View Dependent Claims (14, 15, 16, 17, 18, 19, 20, 21, 22, 23, 24)
