Abstract

This paper presents a free space wire antenna having two larger bandwidths with satisfactory forward gain, return loss and VSWR. With center frequency 914MHz the antenna provides a bandwidth 174MHz from 880MHz to 1054MHz. Another band lies between 1478MHz and 1540MHz range with center frequency 1508MHz. These two larger bandwidths enable the antenna to support a wide range of wireless applications such as GPS, cellular communication, CT2, ZigBee, Wi-Fi and biomedical applications. The simulation of the antenna in 4NEC2 shows VSWR 1.08002, Return Loss -28.298dB and Gain 1.99dB. The characteristic impedance of the antenna is 49.7346 Ω without the use of any matching network. Both the simulation and experimental result shows that the antenna is omni-directional in nature.
