A Low-profile Wideband Pattern and Polarization Diversity Antenna

Yan Zheng, Sen Yan 

Abstract—In this paper a low-profile, broadband antenna with pattern and polarization diversity is reported. The antenna is composed of a L-plate feeding differentially driven patch antenna and a monopole antenna. By sharing part of the radiated element, these two antennas are integrated together. The numerical results show that the proposed antenna can provide a polarization and pattern diversity over the frequency band of 1.7-2.7GHz, and the overall height of the antenna is only 0.11 λ₀ at its lowest operating frequency. Moreover, the method of the differential feeding ensures a good isolation and low envelope correlation coefficient between these two radiation patterns, which demonstrates an excellent diversity performance.

Keywords—low-profile antenna, broadband antenna, pattern diversity, pattern diversity, differential feeding.
