Abstract
A simple structured planar wire antenna for WiMAX, Wi-Fi, WLAN, Bluetooth and satellite communication applications is presented. The antenna has four significant frequency bands with bandwidth of 194 MHz (2.956 - 3.15 GHz), 454 MHz (5.196 - 5.65 GHz), 79 MHz (6.538 - 6.617 GHz), and 424 MHz (12.812 - 13.236 GHz). The antenna is assumed to be feed by a 50 Ω coaxial cable. Application of RC network improves the antenna impedance behavior. It shows unidirectional radiation pattern with sufficient antenna gain. The antenna design cost is very low and about 200 BDT.
