摘要：
A novel low-profile broad-beamwidth circular polarization antenna, named modified microstrip-monopole antenna is presented in this article. Four small circular patches are loaded at the top of the microstrip-monopole antenna. Applying this simple method, the thickness of the proposed antenna can be reduced to only 45.9% of the microstrip-monopole antenna. The low profile characteristics of microstrip antenna can be kept. The 3-dB beamwidth of the proposed antenna is 134 degrees at the central frequency, which is 1.81 times of the classical microstrip antenna. Measured and simulated results are demonstrated, and good agreement is obtained.
