In this paper, a stacked microstrip patch antenna is proposed for C-band RX/TX satellite communications. To broaden the bandwidth in RX/TX bands, aperture-coupled feeding network using foam material was used to design a microstrip antenna. To improve the side-lobe level performance, the feeding network taperd by a Dolph-Chebyshev distribution was used. Since we use separate radiating element for receiving and transmitting bands, each radiating element is operated independently. The RX radiating patch produces vertically polarized wave and TX radiating element produces horizontally polarized wave. The receiving bandwidth of a single element is 800 MHz and transmitting bandwidth is 1200 MHz for VSWR less than 2. The receiving bandwidth of a designed 4×4 array antenna is 800 MHz and transmitting bandwidth is 500 MHz for VSWR less than 2. The receiving gain and transmitting gain of a designed array antenna are about 17〜18 dBi and 18〜19 dBi, respectively.
