Abstract
In this paper, a high-gain dual-band planar Microstrip patch antenna is designed to work at two different frequencies namely 5.6GHz and 7.4GHz. The antenna structure is in the form of Garuda Vyuha and has high directivity. The results propose that the Garuda Vyuha based antenna structure has very low profile and good polarization characteristics. The proposed antenna structure is simulated using ADS software and from the simulated results, the return loss is -15.094dB at 5.681GHz and -12.371dB at 7.337GHz. The Antenna operates at a bandwidth of 22MHz at 5.6GHz and 41MHZ at 7.4GHz. The Antenna provides a directivity of 5.921 at 5.6GHz and 6.2 at 7.4GHz. This antenna structure can be used for dual band applications in Wireless systems operating in these bands.
