Abstract

A novel Slotted-Decagon-Shaped (SDS) antenna is presented for Ultra Wide Band (UWB) applications. This antenna has two slots; the first one is printed on the lower side, and the second on the upper side of the conducting patch. The feeding technique used to feed this antenna is a 50Ω strip line. Return losses, bandwidth, radiation pattern, and, gain of the presented SDS antenna are tested. These characteristics denote it fitting for UWB wireless communication systems. The SDS antenna was fabricated and tested at the laboratories of the Iraqi-ministry of science and technology and the result shows a fine agreement between simulation and measured S11. The SDS antenna has a compact size of 19.3mm×36mm×1.6mm. Measured results show that the SDS antenna has favorable properties of S11 less than −10 dB and a quasi-stable gain of 2 to 4.5 dB over UWB, with the exception of the notched WiMAX (3.3-3.7 GHz) & WLAN (5.1-5.8 GHz) bands.
