Design and Analysis of Leaky Wave Antenna to Generate the Bessel Beam

Leaky wave antenna offers a thin and low profile antenna. It provides sidelobe level reduction and radiation pattern shaping. The leaky wave antenna is studied to generate the Bessel beam for a specific region. Until now, the leaky wave antenna is implemented in the higher frequency region. This paper presents the design and analysis of leaky wave antenna for the lower frequency region. The leaky wave antenna is designed and implemented at an operating frequency of 2.45GHz and 5.8GHz. Both antennas are designed by using an FR4 epoxy substrate of thickness 3.2mm. The proposed antenna represents an attractive, low cost and simple solution to generate the Bessel beam. The leaky wave antenna has various applications in the microwave region.
