High Gain 6X6 Patch Phased Array Antenna For Millimeter-wave 5G Applications at 28 Ghz

In this paper, a high gain 6X6 phased array patch antennas is designed for future 5 G millimeter wave. The proposed antenna array is fed by a combination of three series-parallel and vertical feeding network. The antenna design has a compact size of 46x46 m
²
. 13 beam switched states are generated using required amplitudes and phase excitations for the antenna elements. A good scanning performance of a range of
$\boldsymbol{\pm 20^{\circ}}$
in horizontal and vertical axis is achieved, while maintaining a high gain of 19 dBi for all beams.
