A Double Tuning Fork Shaped Printed Antenna for Satellite Applications

A tuning fork shaped microstrip printed antenna for satellite application is reported. The proposed antenna has a dimension of 24×35×1.6mm³. The optimized dimensions are determined through parametric study and the effects of feed width, tuning fork length, fork gap, and ground slot length on antenna performance are analyzed and results are illustrated. The simulation results demonstrate that reflection coefficient is below -10 dB over 8-11.2 GHz. It is shown that the E-field pattern is bi directional where as H-field pattern is omni directional. The peak gain at frequencies 6.5, 8.5 and 11.5 GHz are 5.46 dB, 5.53 dB and 4.84 dB, respectively. The design and simulation are performed using HFSS software. It is shown that the antenna is preferable for X and K band satellite application.
