Shaped reflector antenna
Webb26 juni 1998 · A method for shaped reflector antenna design Abstract: A method is developed for shaping a single reflector antenna to achieve a specific contour coverage … WebbWithin certain limits, signal reception and the antenna diagram can be controlled such that reception and transmission can be simultaneous. The beam or diagram can be controlled in real time. Another advantage is that the hemisphere can be reproduced in full, i.e. at an angle of elevation ranging from 0° to 180° and an azimuthal angle ranging from 0° to 360°.

WebbThis directivity is comparable with that of a parabolic reflector antenna of the same size and is greater than that of a wideband [2 - 18 GHz] dual polarized FLANN horn antenna where the directivity varies from 10 dB to 23 dB. The directivity increases strongly when we move towards higher frequencies. WebbThis reflective array television antenna consists of eight "bowtie" dipole driven elements mounted in front of a wire screen reflector. The X-shaped dipoles give it a wide bandwidth to cover both the VHF (174–216 MHz) and UHF (470–700 MHz) bands. It has a gain of 5 dB VHF and 12 dB UHF and an 18 dB front-to-back ratio.
