Abstract
In this paper, a novel proximity-coupled fed microstrip Circular Patch Antenna (CPA) is proposed for 5G applications. The proposed CPA resonates at a frequency of 3.5 GHz. The simulation of the proposed CPA is done using High Frequency Structure Simulator (HFSS) software. The parametric optimization feature available in HFSS Software is used for determining the optimized dimensions of the proposed CPA. The optimized compact CPA is having a substrate of length 30 mm, and width 45 mm. The radius of the radiating patch is 13.005 mm. The proposed antenna is having an excellent S 11 characteristic and impedance matching. The S 11 is found to be -40.2827 dB. The CPA also has a substantial gain of 5.8 dB. The VSWR is nearly ideal (1.02) and the CPA has an efficiency of 88.40% and serves a bandwidth of 200 MHz. With such alluring features, the proposed CPA can be a suitable candidate for a variety of 5G applications such as the Internet of Things (IoT), Machine to Machine (M2M) Communication, etc.
