Design of Compact Wideband Planar Antenna for Wireless Application
Abstract
The paper presents the design of ultra wideband antenna for wireless applications operating in the frequency range 4.816 GHz to 11.08 GHz with good radiation performance. The designed UWB antenna consists of three strips resonating at different frequencies and a microstrip feed line on one side of the FR4 substrate and partial ground plane on the other side. The impedance bandwidth of the antenna for VSWR ≤ 2 is 6.262 GHz with the maximum gain of 2.247 dBi. The radiation pattern in the elevation plane is figure of eight with beam width of 740 and in azimuthal plane it is Omni directional. The consistency of the pattern exists within the operating bandwidth. The transverse dimension of the antenna is 10 x 10.4 mm2 excluding the feed line. The designed antenna was simulated using IE3D software and tested using Network Analyzer. The proposed UWB antenna can be integrated with hand held devices and consumer Electronic Equipment for short range applications due to its compact nature.
