A wideband dual polarization base station antenna

This article investigates the slotted bow-tie dual-polarization antenna with achieving the wide band. The proposed antenna consists of upper antenna and lower antenna in one PCB substrate. This antenna achieves a −10 dB return loss within the operating band of 1.6–2.3 GHz, which has a 700 MHz bandwidth. Isolation between antenna 1 and antenna 2 is about −30 dB within the operating frequency band. Antenna 1 and 2's gains are above 8 dBi in the entire frequency bandwidth. © 2015 Wiley Periodicals, Inc. Microwave Opt Technol Lett 57:22–26, 2015
