Abstract
In this paper, a dual-polarized 8 × 8 antenna array with an orthomode transducer (OMT) is presented. To enable dual-polarization, the feed networks of the antenna array is incorporated into the subarray antenna design. A planar substrate integrated crossover is introduced in order to simplify the design and achieve high performance. Triple-resonance is excited in the subarray antenna. The proposed array antenna can work in the frequency bandwidth of 19.2-20.7 GHz. The measured results show that this antenna array has a cross-polarization level of -43 dB, realized gain of 22.8 dBi and aperture efficiency of 51%. The designed dual-polarized antenna array can be used in the geostationary satellites that is able to radiate fixed beams illuminating areas with high density of users and devices.
