BANDWIDTH AND GAIN ENHANCEMENT OF CUP SHAPED UWB MICROSTRIP PATCH ANTENNA WITH DEFECTIVE GROUND PLANE FOR SUB-6 GHZ 5G APPLICATIONS
View through CrossRef
This paper presents the design of slotted ground plane and a circular ring slotted microstrip patch antenna for new radio (NR) band, sub-6 GHz, WLAN and Licensed Assisted Access (LAA) 5G applications. The design consists of cup -shaped microstrip patch antenna with a defective ground structure (DGS). The circular ring slot at the top of the patch and the modified rectangular slots at the bottom are helpful to improve the performance of the antenna, thereby increase the efficiency, bandwidth, gain and improved s-parameters. The proposed antenna is designed on FR4-epoxy substrate and inset feeding technique. The design and simulation of my proposed work are done using HFSS (ANSYS-Electronics suite 19.2×64 version). The antenna has a bandwidth of 2.56 GHz with maximum gain of 2.27 dB. The antenna operates for the bandwidth from 4.04GHz to 6.6 GHz which covers NR-New Radio band (3.4-4.2 GHz), Sub 6 GHz 5G band (n-79) (4.44-5.0 GHz), WLAN (5.15 - 5.35 GHz) and Licensed Assisted Access (LAA) band.
