A major disadvantage of the micro strip-patch antenna is its inherently narrow impedance bandwidth of only a couple of per cent. Intensive research is going on to develop bandwidth-enhancement techniques by keeping its size as small as possible. In this paper, square ring MSA with two nearly square slots is designed, simulated, fabricated and tested. It is a singly-fed, wideband and high gain micro strip Antenna. The proposed antenna is left-hand circularly polarized and operates in 5-6 GHz frequency band. The impedance bandwidth with an input VSWR of two is obtained as 16.23% while the 6dB axial ratio bandwidth is measured over 4.52%. |
