Bandwidth Enhancement of U Shape Notched Microstrip Patch Antenna for Low Frequency Band

Abstract: In this research paper, microstrip patch antenna with U-shape notched is analysed. Proposed antenna is suitable for band (1.965 � 2.508 GHz) for frequency band. The proposed antenna meet the required impedance bandwidth is 24.279 %. The dimension of proposed antenna is (29.5 � 38.0 � 1.6 mm3). This antenna exhibits bandwidth at 2.367 GHz and Gain is 4.01543 dBi. The archived band can be optimized by change parameter of U Shape notched microstrip patch antenna. The variation in the design structure from U shaped antenna is notching in the structure and varying the width of slot. The proposed antenna by introduces notching in the rectangular U shaped radiating patch, is suitable for Wireless application which works around frequency 2.4 GHz and its VSWR is around 1.237.
