12GHz Planar Array Antenna for Satellite Communication
A novel microstrip array antenna of 32 elements is designed and built for broad-casting satellite orbital positions. It is working in the 12.43-12.53 GHz band (space-to-Earth). A corporate feeding network is used to give equal amplitude and phase to each element. The theoretical analysis is based on IE3D (Zeland) software and genetic algorithm to optimize the performance of the planar array. A dummy column of elements is assumed around the excited 32 elements. The effect of these dummy elements is tested using IE3D (Zeland) software on the return loss and voltage standing wave ratio (VSWR). The simulation shows the return loss and VSWR decrease as the number of columns of parasitic elements increases. On the other hand the center frequency increases as the number of parasitic elements increases. The return loss and VSWR are measured and compared with the simulated results. They are very close. Both the theoretical and experimental results are presented and discussed.
