A Low Profile Wideband Planar Antenna for 5G Wireless Communication Applications

Abstract

This paper presents a low profile wideband planar antenna for 5G applications. The designed antenna consists of a circular patch element and a partial ground plane with two rectangular edge elements and has a compact size of 20 × 35 × 0.8 mm3, The antenna with the optimized dimension of the patch element and the ground plane is able to excite for a wide bandwidth of 2900 MHz (2.99 - 5.89 GHz) which cover all the lower 5G bands between 3 GHz to 5 GHz at reflection coefficient, S11 < -10dB. Due to its simple structure, smaller size, symmetric radiation pattern and stable gain, the proposed antenna could be a potential competitor to be used in 5G wireless devices.
