| Abstract(in English) | In this paper, authors propose a low sidelobe dual-polarized planar array antenna for transportable terminals in Ku-band satellite communications. In this antenna, rectangular coaxial lines were adopted as low loss feed lines in order to reduce loss of feeding circuits and coupling between feed lines. We have developed a dual-polarized element antenna shielded by a cavity, in order to reduce coupling between element antennas and feed lines. Also, we have developed an element antenna arrangement method forming antenna aperture distribution by number of antenna elements in each row. These developed methods allow achieving sidelobe levels less than -23dB which would be lower than those of conventional dual-polarized planar array antennas using feed networks such as strip lines. |
