K-/Ka-Band Circular-polarized Shared-Aperture Phased Array Antenna for Satellite Communication

K-/Ka-Band is significant block of spectrum in the satellite communication. In this design, K-/Ka-band circular-polarized shared-aperture phased array antenna is proposed. The center frequency of high and low band is 19.5 GHz and 29 GHz, and the operational bandwidth is 3 GHz and 5 GHz, respectively. Dual-band shared-aperture uniform arrays is designed with the square lattice. A wide-angle scanning of ±60° in both operating bands can be obtained.
