Design and Performance Analysis of High Gain Yagi Shaped Patch Antenna for Wi-Fi Application

Micro-strip Patch Antenna development in wireless communication has become one of the demanding technology as it has a compact size as well as drawing efficient performance of the antenna. A further study been done on micro-strip antenna where it consists of a Yagi-shaped microstrip patch on the substrate of fire retardant type-4 (FR-4). The designed antenna is simulated using the Computer Simulation Technology (CST) software to attain desired band, bandwidth and good return loss. Several parametric studies of the proposed configuration were carried out to characterize the antennas and to verify the simulation result. The final result produces a good return loss and bandwidth which operates at resonant frequency of 5.56 GHz with impedance bandwidth of 0.122 GHz. The antenna is fabricated and the performance of the antenna is tested and measured. The result shows a closed agreement with simulated result.
