Abstract
In this paper, a new wideband Circular monopole antenna is proposed for Wireless communication. Commercially available finite difference time domain (FDTD) based software Computer Simulation Technology (CST) microwave studio has been adopted in this investigation. A wide frequency bandwidth of 3.25 GHz (1.65 GHz to 4.9 GHz.) has obtained in measurement. The operating frequencies of the proposed antenna are GSM-1800, GSM-1900, UMTS, Bluetooth (2400–2800) MHz, WLAN (2400-2485) MHz and WiMAX frequency bands. The antenna has been printed on FR-4 (lossy) Substrate material with relative Permittivity of 4.6 and thickness of 1.6 mm. The computational results has been validated the measured one. In addition, the electromagnetic absorption analysis has been investigated for the proposed antenna.
