Title:  Wideband Patch Antenna Array for 5G Terminal Devices

Abstract:
Wide band and multi-band antennas are highly in demand for mm-wave communications, as different frequency spectrums have been allocated according to different standards. In this communication, a simple and low-profile patch antenna with a relative bandwidth of 59.6% is designed for mobile terminals. An elliptical slot is etched in the wide patch antenna, creating new modes and leading to broadband operation. A U-shaped strip is added in the slot as a parasitic element, which improves the impedance matching at the higher band and further enlarge the bandwidth. With all the resonances, the antenna operates from 27.7 GHz to 51.2 GHz, with the gains varying between 5.8 dBi and 7.8 dBi over the operating band. Antenna arrays are then built from four patch elements, and integrated with the longer frames of the mobile handset.
