A multifrequency semicircularmicrostrip antenna is designed and simulated in this paper using HFSS simulation software. The proposed antenna consists of two quarter rings in different radius with one as perfect ground and other as defect ground structure, with an inverted T-shaped slot. The relationship of the resonant frequency with different physical size parameters for the single one-quarter-ring microstrip antenna is also reported. This designed multiresonant antenna proves increase in bandwidth when defect ground is used as compared to normal or conventional ground plane. The simulation show that proposed designed antenna operates at six different frequencies of 1.7, 1.93, 2.3, 3.03, 3.57 and 3.67 GHz, respectively for normal ground whereas wide bandwidth of 500 MHz is achieved for 1.9 GHz operating frequency.
