摘要
By mounting a regular circularly polarized microstrip antenna on a three-dimensional (3-D) square ground structure, beamwidth enhancement of the circular polarization (CP) radiation can be obtained. Experimental results show that, owing to the 3-D square ground structure, the 3 dB beam width of the CP radiation can reach more than 110 degrees, which is about 30 degrees greater than that of a corresponding regular microstrip antenna. Details of the proposed 3-D square ground structure are described, and the effects of various dimensions of the proposed square ground structure on the beamwidth enhancement of CP radiation are experimentally studied.
