Abstract
This letter presents a new wideband, printed, microstrip-fed, circular patch antenna for multifunctional wireless communication applications. The commercially available CST Microwave Studio software package, which is based on finite difference time-domain (FDTD) analyses, has been adopted in this study. The experimentally determined impedance bandwidths are 2.2 GHz (1.75 GHz to 4 GHz) and 750 MHz (4.15GHz to 4.90 GHz), which cover the GSM-1800, GSM-1900, UMTS, Bluetooth (2400-2800) MHz, WLAN (2400-2485) MHz, WiMAX (2500-2690) MHz and WiMAX (3400-3600) MHz frequency bands. The experimental measurements taken using the proposed antenna are in good agreement with the computational results.
