Abstract
In this paper, a circularly polarized compact printed antenna is adduced for small satellite communication system. Due to low profile and lightweight property of microstrip antenna it has been selected for satellite communication. For the analysis process Computer Simulation Software (CST) microwave studio and High Frequency Structural Simulator (HFSS) have been used and their working procedure is Finite Integration Technique (FIT) as well as Finite Element Method (FEM). The anticipated antenna consists of a truncated corner cut patch with a T-shaped slot in the ground plane. Both CST and HFSS packages of simulation software have been justified to find the axial ratio and reflection coefficient result. The CST and HFSS simulated results show that the obtained impedance bandwidths are 130MHz (2.30–2.43 GHz) and 140MHz (2.28–2.43 GHz) respectively, good enough for S-band satellite applications. Substrate material FR-4 (lossy) with dielectric constant of 4.6 with a height of 1.6mm has been used to print the antenna. An axial ratio of 3 dB beam width more than 160 º was displayed by the proposed antenna. The simulation and measured result are very much identical.
