Antenna structure for communication

摘要

The present invention relates to an antenna structure for communication applications, which is used to increase the half-power beamwidth (HPBW) in the H-plane of the slot coupled microstrip patch antenna with a finite size ground plate and a finite size reflector. The antenna combination according to the present invention comprises a front-plate composed of a curved plate, a flat plate, and several patches. By using the present invention, the half-power beamwidth in the H-plane would be increased.
