Abstract :
The implementation of methods for the EM analysis of reflector antennas based on the integration of (surface and edge) induced currents is compared with that of a numerical analysis based on the Method of Moments, chosen as a reference due to its ability of properly addressing the interaction between reflector and feed structures. This is explored herein in connection with the synthesis of shaped reflectors encountered in certain terrestrial systems prescribing omnidirectional coverage. These antennas are usually employed in a LMDS system base station to operate with the distribution of digital TV signals.
