Abstract

This paper presents the design and performance of a modified circular microstrip patch antenna (radius 14mm) with modified ground plane with overall size 34mm × 39 mm × 1.59 mm. The proposed antenna is simulated by applying CST Microwave Studio simulator. This antenna has broad impedance bandwidth of 2.70 GHz (2.42 GHz - 5.12 GHz) with flat gain (close to 2.25dBi-3dBi) in the desired frequency range. This antenna may be a useful tool for lower band of Wi-Max communication systems (2.4 GHz -2.69 GHz) as well as for lower band of UWB communication systems (3.1 GHz - 4.85 GHz).
