Abstract—Two novel configurations for increasing the
impedance bandwidth of the microstrip patch antennas have
been proposed for operating in the 3G mobile communication
range. In these configurations, additional resonators of semicircular
shape rather than conventional rectangle are gap
coupled to the non-radiating edges of the fed rectangular patch.
A comparative study is done between the antennas of the same
size with two semicircular parasitic patches and an antenna
having a combination of semi-circular and rectangular
parasitic patches. Compared to the available broadband
antennas, the proposed antenna structure gives a better
bandwidth.
