Abstract : Now a day’s, Due to tremendous growth in wireless communication in the aspect of need of higher data transfer rate and portable and compact device, the requirement of antenna having simple structure, compact size, stable radiation pattern while retaining extremely broad frequency range is on high demand. However UWB antenna design especially for portable device has some challenges including the ultra wide band performance of impedance matching and radiation stability, compact antenna size, constant group delay and low manufacturing cost for consumer electronics application. Microstrip antenna became very effective candidates for wireless communication systems due to their low profile, wide impedance bandwidth, and compact size, ease of fabrication, etc. In this paper, a novel design and analysis of a coplanar wave guide (CPW) fed ultra wide band microstrip patch antenna is proposed for UWB Applications. The antenna consists of Elliptical patch of major and minor axis of 32 mm and 24 mm fed through CPW line having width 3 mm. The proposed patch antenna is elliptical in structure which gives larger degree of freedom and flexibility in the design, compare to circular configuration and can also provide circular polarization by means of proper selection of feed line of ellipse while CPW fed provide good impedance matching. The antenna is overall size of 50×35×1.6 mm3 and assumed to fabricate on RT Duroid substrate whose dielectric constant is 2.32.The proposed antenna is simulated and exhibit impedance bandwidth of 2.4 GHz to 10.6 GHz (8.04 GHz) for S11≤ -12 dB with stable radiation patterns, better impedance matching, low VSWR and reasonable gain over UWB.
