LMDS base station antenna design

Résumé

The design of a feed network for a 24 x 2 stratified linearly polarized patch array is presented in this article. This design is a candidate for an LMDS Base Station antenna and complies with ETSI Standard requirements such as polarization, bandwidth, gain, -3 dB beamwidths and Side lobe levels. The feed network has been designed to produce appropriate unequal power excitation for each patch and a match condition at the feed point. Unequal distribution of the power improves the side lobe level. From simulation, the array antenna yields -23 dB return loss in the LMDS band, narrow -3 dB beamwidths of 2.9° and 46° in the elevation plane and azimuth plane respectively, high gain of 23 dB and 7.5 % bandwidth satisfying with ETSI Standard.
