Abstract:

A compact simple broadband circular V-shaped slot antenna microstrip antenna is proposed for circular polarization (CP). The Circular polarized patch consist Z type feed line on top of substrate and two right angle V shaped slotted cut on gnd plane which is shown in backside of substrate. The multi response is achieved by using stub element in feed line Using stub element the broad CP and impedance bandwidths overlap by the symmetrically etched right angled V-shaped closed slot along the center line and the Zshaped feedline placed in a proper position. The proposed wideband CP antenna exhibits a much wider impedance bandwidth (1.61-4.85 GHz) of about 135.5% (S11 < −10 dB). The broadband CP antenna offers good gain over the entire frequency band of operation for Wireless applications. The proposed antenna possesses a high gain of 5.4 dB with the overall size is 44mm*50*1.6mm2.Proposed CP Broadband antenna covering UTMS, PCS, 2G,3G, WLAN, LTE, and WiMAX band applications.
