A 36 port Dual Polarized High Gain Sub-6GHz Multibeam Base Station Antenna

This paper presents the design of the dual-band dual-polarized high gain sub-6GHz multibeam base station antenna for wireless communications at the frequency band of 3.3-4.2 GHz and 5.15-5.93 GHz. Based on the required specifications such as gain, the azimuth beam coverage, the cross-over point between beams, and the side lobe level, a 36-port dual-band dual-polarized multibeam antenna has been designed, implemented, and tested.
