The rapid growth in the field of microwave communication has put a demand to develop antenna with wideband response due to their high data rates, great capacity, simplex design and low power consumption. The ultra-wideband systems are usually used for personal wireless communication in home or office networks. However an antenna with ultra-wide band response mainly finds its application in electronic warfare and military purpose. The main drawback of UWB antennas is their interference with existing communication channels like GSM (900-1800GHz), UMTS (1.92-2.71GHz), Wireless Local Area Network (WLAN5.15-5.825GHz), Worldwide interoperability for Microwave Access (Wi-MAX, 3.3-3.7 GHz) IEEE 802.11a in the United States (5.15-5.35GHz, 5.725-5.825GHz) and HIPERLAN/2 in Europe (5.15-5.35GHz, 5.47-5.725GHz).
