Abstract :
This paper presents a low-cost ultra-wideband microstrip antenna for wireless communications. Printed on a 40times50times1.83 mm3 Isola Gigaver 210 substrate, the antenna features a microstrip feed line with two 45deg bends and a tapered section for size reduction and matching, respectively. The ground plane is partial and comprises a rectangular part and a trapezoidal part. The patch is a half ellipse, where the cut is made along the minor axis. Several slots are incorporated into the patch. The placement and sizes of the slots are assisted by the knowledge of fractal geometries. The return loss, input impedance, gain, efficiency and radiation characteristics of the antenna are presented. It is shown that the antenna can operate in the bands used for UMTS, WLAN, WiMAX, and UWB applications.
