Abstract

A low-profile, single-fed, dual-band, linearly/circularly polarized antenna for future 5G networks in the millimeter wave frequency regime is presented. The antenna comprises of two truncated-corner square patches. A cross-slot is etched on the inner patch. It is shown that this cross-slot generates additional resonances and lowers the axial ratio (AR) of the radiating structure. The proposed antenna is fed asymmetrically by a two-section microstrip line. The overall size of the antenna is only 8 mm × 8 mm. The proposed antenna operates at 28 GHz and 38 GHz. The antenna is linearly polarized in the lower band with an impedance bandwidth from 27.55 GHz to 28.15 GHz for |S11| < -10 dB. The antenna is circularly polarized in the upper band with an impedance bandwidth from 37.2 GHz to 38.3 GHz for |S11| < -10 dB and axial ratio (AR) bandwidth from 37.1 GHz to 38.1 GHz for AR < 3 dB. The antenna has a stable radiation pattern and a gain of greater than 6 dBi over both frequency bands.
