This paper presents a novel design of polygon shaped microstrip slot antenna for dual band operation. The dual bands are achieved by placing ring slot in the conventional polygon microstrip antenna. The impedance bandwidth of each operating band is found to be 6.58% and 27.53%. These bands are enhanced to 22.68% and 36.03% respectively by truncating two corners of polygon patch, which also reduces the overall size of the patch by 27.48% when compared to conventional square microstrip antenna. The enhancement of impedance bandwidth does not affect the nature of broadside radiation characteristics. Design concept of antennas is given and simulation results are discussed.
