Abstract :
Hexagonal microstrip antenna (HMSA) with a single feed has been proposed for circular polarization. The configuration has been realized by inserting perturbations along two opposite vertices of a diagonal of hexagonal patch. Smith chart, axial ratio, impedance and radiation characteristics are presented and discussed. From the results, it has been observed that the impedance bandwidth, defined by 10 dB return loss, can reach an operating bandwidth of 40 MHz with an average center operating frequency of 2.45 GHz. The axial ratio band width of 10 MHz has been achieved for HMSA. The gain and directivity of studied antenna is also observed with peak gain of about 6 dB and directivity of 7.3 dB respectively.
