Dual-Polarized Array Antenna with Quasi-End-Fire Radiation for 28 GHz 5G Mobile Terminals

Abstract

In this palimpsest, an uncomplicated design technique of dual-polarized antenna array is suggested for the fifth-generation (5G) mobile terminal. Its structure contains a pair of conventional slot antenna arrays arranged with a 90° difference on the top portion of the smartphone printed circuit board (PCB). The employed substrate is Rogers 5880 laminate with an overall size of 75×150×1.2 mm 3. The proposed design is designed to work at 28 GHz. The essential characteristics of the design in terms of S-parameters, radiation patterns, efficiency, and antenna gain are investigated. The obtained results show good features of the antenna array for non-identical polarizations.

Dual-Band MIMO Antenna Design for 5G Smartphones Mobile Communications

“…Artificial intelligence, mobile video streaming, and the Internet of Things (IoT) are the driving reasons behind this huge expansion in wireless communication [3][4]. Fifth-generation mobile networking is the most up-to-date crucial bandwidth elucidation that advances radio transmission technology and satisfies the growing requirement for cell phone communication setups in the coming years [5][6][7][8]. However, once 6G becomes available, fifth-generation mobile networking will be rendered obsolete.…”
