State of the art of corrugated horn antennas that combine horizontal and vertical corrugations

In the present paper the state of the art, possibilities, advantages and disadvantages of the patented corrugated horn antennas that combine horizontal and vertical corrugations is being covered. These rather new type and probably not very well known yet, corrugated horn profiles; combine in the same horn antenna both horizontal and vertical corrugations. This horn antenna produces with reasonable bandwidth, low crosspolarisation, and low sidelobe levels in a physical size smaller than any other solutions. In fact, designs from 15 to 30 dB directivity have been prepared and some of them have been manufactured, tested and arranged for an emerging market that is being served by Flann Microwave Ltd. at present.
