Design and Simulation of Multiband, Circular Microstrip Patch Antenna for Wireless Applications

Abstract

This article summarizes the detailed design of a circular-shaped microstrip patch antenna. This antenna is designed to radiate at 10 different frequencies that can be used for advanced wireless communication. The proposed antenna can be used in Bluetooth, BLE, Wi-Fi, Zigbee, 2G 3G 4G LTE, and 5G communication. This antenna can radiate at 10 different frequencies such as 3.26, 5.36, 7.45, 9.65, 11.79, 13.20, 13.20, 13.72, 15.32, and 19.1 GHz. These are specially designed frequencies on which the proposed antenna should work. That means this antenna can be modified and redesigned to work for a dedicated application operating between the ranges of 3.26 to 19.1 GHz. The at all the 10 frequencies mentioned above, they observed values of s parameter are below −10 dB. The voltage standing wave ratio at about resonating frequencies observed to be between 1 and 2. Since it shows narrow bands at the designed frequencies; this antenna can be used for a specific application with a specific frequency without interference with other systems.
