Design and analysis of multiband reconfigurable slot antenna for S, C, and X-band applications

Abstract

In this paper, a reconfigurable microstrip patch antenna with two linked slots and a microstrip feed line is reported, which is useful for Bluetooth/WLAN/ISM (2400–2484 MHz), high frequency LTE band (2496–2690 MHz), WiMAX (2.50-2.69 GHz), S-DMB (2605–2655 MHz) and X band (8.0-12.0 GHZ) applications. The antenna is reconfigured by adding a switch in the feed line. The simulation of proposed antenna has been performed with CST Studio Suite 2022. The antenna resonates at 4.70 GHz and 9.765 GHz under ON condition and resonates at 2.64 GHz, 4.71 GHz, and 10.07 GHz under OFF condition. The antenna is fabricated and measured results are found in close agreement with simulated results.
