Antennas, which send and receive the electromagnetic waves through space play a vital role in wireless communications. It is the basic element used to establish a wireless link between communicating devices. In today's communication industry, antennas are most important due to their several attractive features like small size, low bandwidth etc. and are used widely over the past decade. A micro strip patch antenna with a small aperture is presented in this project. The area of proposed antenna

... s 26x26mm 2 .Here a small rectangular slot of size 6 x 2 mm 2 is created at the center. The bandwidth of proposed antenna by using coaxial feeding is 38.2%. The technique used for improvement of bandwidth is shorting pin. Shorting pin is created either along X-axis or Y-axis. It is created at any position with probe height. The feeding technique used is coaxial The obtained feeding. The coaxial feeding is given at position (x 0 ,y 0)=(2.7mm,0.5mm).Return loss plot, Radiation Pattern and VSWR plots were observed. The proposed antenna resonates at 5.25 GHz with improved bandwidth of 53.2%. This frequency meets the specifications of wireless applications like Wi-Fi, Wi-MAX. Hence this project mainly emphasizes on bandwidth improvement of patch antennas.[1] INTRODUCTION:
