Design of Rectangular Patch Array Antenna for Satellite Communication

Microstrip patch array antennas are widely used in satellite communication, because of its advantages compared to the conventional antennas. Literature study of previous years of patch array antenna (PAA) shows that several techniques were used for making the small size of patch array antenna. This paper presents the micro strip array antenna 2x2 operating at 12 GHz with a bandwidth equal to 693.6 MHZ (5.9 %), a gain equal to 8.98 dB, directivity equal to 10.83 dB and finally an efficiency equal to 83 %. A 2x2 linear array is designed for line feeding, the substrate used is FR4 with a thickness of 1.6mm and a dielectric constant of 4.4. This array antenna is made for satellite communication, X-band applications, and KU applications. The antenna array is designed by using HFSS 12 (High Frequency Structure Simulator) and also the simulation has been done by the same software.
