“…Comparisons among recently reported low XP antennae are shown in Table 2. Compared with other reflector antennas reported in Bahadori and colleagues, 11,12,17,18 it can be seen that the proposed reflector antenna exhibits an ultralow XP of about −40 dB. Although a slotted or substrate‐integrated waveguide antenna 19,20 can achieve better XP performance, it is difficult to employ in multibeam antenna system.…”

This paper presents a design to realize extremely low cross‐polarization level in multibeam antenna. The antenna consists of two reflectors placed on top of each other. The front reflector is a panel made of metal grid, which is used to separate two orthogonal polarizations. The rear reflector serves as the actual multibeam antenna surface. The multibeam antenna and feed array operated at Ku band are designed and fabricated. The test results show that the gains of the 28 beams can be better than 40.42 dBi, and the cross‐polarization level can be lower than −40 dB. The proposed method provides a novel idea for the design of ultralow cross‐polarization multibeam antenna.
