| 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.
