Abstract
A new dual-polarized horn antenna fed by a microstrip patch is proposed. The patch is excited in two orthogonal polarizations by small gaps between the patch edge and the microstrip open end. A horn antenna operating at 14.9 GHz is designed, fabricated and tested. Measurements show that the horn has a reflection coefficient of less than-10 dB, and a port isolation greater than 30 dB, over 14.6-15.2 GHz, and a gain of 12.34 dBi and 10-dB beamwidths of 87 • and 88 • at 14.9 GHz.Keywords
