Abstract :
Paper reports the design and performance of a modified circular microstrip patch antenna with modified ground plane. Proposed antenna with overall dimensions 22 mm × 36 mm × 1.59 mm is simulated by applying CST Microwave Studio simulator and fed through a quarter wave line. This antenna has an impedance bandwidth of 3.00 GHz (2.40GHz - 5.40GHz) with flat gain (close to 3dBi) in the desired frequency range. The E plane radiation patterns simulated at frequency 3.5GHz are almost omni directional while H-plane patterns resembles with that of a dipole antenna. Both patterns are directed normal to patch geometry. This antenna may be proved useful in modern wireless communication systems.
