Design of an Antenna Array for Radar Application

Abstract

This paper presents, a rectangular shaped microstrip patch antenna was designed for radar application at an operating frequency of 9.6 GHz. Four radiating element of patches are used to design the antenna array. The dielectric constant 4.6 and having the substrate height 1.6mm. This antenna array design is combined with 4 radiating elements. These radiating elements are used in this design to increase gain and directivity. The substrate taken for the design is compared with the frequency range to get the appropriate result, so we have chosen the FR4 substrate with a Dielectric constant of 4.6, Height of 1.6mm, and Loss Tangent of 0.018. The FR4 substrate is chosen because of its efficiency in cost and performance. The gain and directivity of the antenna array have been increased for this design. The Advanced Design System software tool is used for designing and simulating the antenna array.
