Microstrip Planar Broadband Yagi-Uda Antenna for X-Band Communication

Abstract

In this paper, a planar Yagi-Uda antenna based on classic Yagi-Uda dipole antenna is accessible which is very useful for microwave wireless applications. This antenna provides relatively high gain and more directive radiation pattern at X frequency band with proper impedance matching. This antenna has been developed at supporting dielectric constant of 4.4, supported substrate thickness of 1.6 mm and loss tangent of 0.02. The proposed antenna is completely compatible with microwave circuitry and wireless communication system. This antenna is simulated by using IE3D simulation software. Return loss, smith chart, gain frequency graph also presented.
