Abstract :
This paper presents the design and study of a dual band E-shaped patch antenna for UWB application. The antenna uses foam of 5 mm thickness as substrate, resonates at 5.3 GHz and 7.4 GHz with impedance bandwidth of 760.43 MHz and 1.39 GHz respectively. Better impedance bandwidth of 2.75 GHz (45%) is obtained by incorporating slots in the ground plane. Diversity structure is also realized. The antenna can be used for high speed (IEEE 802.11a) wireless computer local area network (WLAN) and other wireless application.
