Summary:
In this paper, a dual-band and dual-polarized microstrip subarray antenna is designed for Ku-band phased array antenna system used in satellite mobile communication. The antenna has a vertical polarization for receiving band and a horizontal polarization for transmitting band. Aperture coupled feed, symmetry feed and parallel feed techniques are used to achieve high gain and high isolation level. The simulated results show that the proposed 4×4 subarray antenna obtains good performance. The return loss values of both ports are lower than - 15dB. The isolation between two ports is higher than 30dB in receiving band. The proposed array antenna obtains the gain of 16.7dB in receiving band, and 18.3dB in transmitting band.
