Abstract

A dual-polarized small base station antenna is presented that has a metallic cube and high isolation. The antenna is composed of a micro-strip feed line board, planar dipole radiators, micro-strip coupling feeds, a metallic cube, and a radome. The measured impedance bandwidth is 2.36-2.95 GHz at port-1 and 2.4-2.83 GHz at port-2. The proposed base station antenna has a high isolation of greater than 40 dB at the operating frequency. The measured peak gain is 9 dBi, and the cross polarizations are all less than 25 dB below the co-polarization level.
