In this letter, a circular microstrip patch antenna with a conical cup is proposed. The results of a simulation and experiment show that the conical cup has a beneficial effect on the antenna's gain and principal plane beamwidths. The maximum gain of this antenna was 12.6 dBi, which is about 3 dB higher than one with a cylindrical cup. The 3-dB beamwidths of the E-and H-planes were 34and 44, respectively.
