Abstract
This paper presents a broadband antenna for 5G indoor micro base station, which has a low profile and simple structure. The proposed antenna avoids the traditional high-cost multilayer technology and is a low-cost configuration. It consists of a center fed circular patch with four shorting pins to properly stimulate the radiation mode of TM01 and TM31 internally. Next, four equally sized fan-shaped slots are opened in the radiator to further expand the bandwidth and improve the input impedance. |S11| < -10 dB simulation impedance bandwidth is about 51% from 3.11 to 5.24 GHz and covers 5G n78 (3.3-3.8 GHz) and n77 (3.3-4.2 GHz) and the n79 (4.4-5 GHz). The voltage standing wave ratio (VSWR) < 1.8 in the whole operating frequency band, which has good matching characteristics.
