A Multi-Band Common-Aperture Phased Array Antenna For Satellite Communication

This paper designs a multi-band common-aperture phased array antenna for satellite communication. It contains three different types of antennas. A dual-band circularly polarized patch antenna in L frequency band, A dual-layer patch phased array antenna in S frequency band and a cross dipole phased array antenna in S frequency band. It has the advantages of small volume, low profile and high space utilization rate. The antenna has various modes satisfied the anti-interference requirements in satellite communication.
