This paper presents the design and performance of CPW fed rectangular microstrip patch antenna having V shaped notch and modified ground plane of overall size 36mm × 30 mm × 1.59 mm. The proposed antenna is simulated by applying CST Microwave studio simulator. This antenna has broad impedance bandwidth of 2.64 GHz (2.25 GHz – 4.90 GHz) with flat gain (close to 1.5dBi) in the desired frequency range. This antenna may be a useful tool for 2.4GHz (2.40-2.48GHz) WLAN communication band as well as for 2.3GHz (2.3-2.4GHz)/ 2.5GHz (2.5-2.69GHz)/ 3.3GHz (3.3-3.4GHz)/ 3.5GHz (3.5-3.6GHz)/ 3.7GHz (3.6GHz-3.8 GHz) Wi-MAX communication bands after further improvement in its gain .
