A microstrip antenna element for satellite communication

This paper gives a detailed analysis on the impedance and radiating characteristics of a micro-strip patch antenna by computer simulation. Some relationships between its size and characteristic parameters have been found. A new structure of micro-strip antenna is presented based on the analysis, which can be used in VSAT station and satisfied with the following requirement of C-band satellite communication: dual-frequency, wide-band, dual-polarization and isolation. The result gives a good accordance with the conclusion presented in the simulation.
