摘要：
This paper presents a circularly polarized dual-band shared aperture antenna for satellite applications. The antenna achieves dual S- and Ka-band operation by housing both a circularly polarized high-frequency reflectarray and a circularly polarized low-frequency patch antenna array in the same aperture area. The high-frequency reflectarray part of the antenna has unit elements within the aperture area of the low-frequency patch antenna array which allows for a high realized high-frequency gain. The antenna has a layered structure with a middle layer of Polypropylene, this enables the low-frequency part of the antenna to achieve a wide impedance bandwidth and a high realized gain. The antenna has a total size of 136x136 mm and the three layers of the reflective surface have a total height of 4.624 mm. The antenna has an impedance bandwidth of more than 415 MHz (12%) and 4.75 GHz (19%) and a peak realized gain of 14.80 dBi and 26.68 dBi at 3.5 GHz and 25.4 GHz, respectively.
