A compact triple bands C shaped multiband monopole antenna for WLAN and WiMAX application

Abstract

Antennas play a crucial role in communication as they serve as both transmitters and receivers. They are capable of supporting numerous applications and demanding higher bandwidth among which monopole antennas have emerged as a superior alternative to traditional antennas. A novel coplanar waveguide (CPW)-fed triple-band monopole antenna is proposed for WLAN and WiMAX applications. The antenna features a compact and simple Cshaped strip structure, allowing for easy fabrication. The prototype exhibits triple operating bands covering the required bandwidths of 2.4/5.2/5.8 GHz WLAN and 3.5/5.5 GHz WiMAX standards. Good radiation performance and antenna gain are achieved across the three frequency ranges. Another compact monopole multiband antenna is designed, consisting of five rectangular patches forming a C-shaped structure. It operates at frequencies covering WiMAX, WLAN, short-range radar, and wireless data transmission applications. The antenna demonstrates significant bandwidth to accommodate the respective frequency ranges required for these applications. The antenna design is simulated using HFSS v13 software.
