Modern K/Ka-band satellite communications have become increasingly demanding in recent years with regard to the performance of the terminal antenna used in the link. These terminals should be high-gain and broadband, as well as guarantee polarization diversity over a large field-of-view. A lowprofile is also highly desired to integrate the antenna system into a variety of moving platforms such as aircraft and trains. An ultra-low-profile continuous transverse stub array is proposed here to tackle these challenges. The antenna array is realized in printed circuit board technology by adopting a contactless transition between the stacked-up layers without resorting to blind or buried vias. The proposed antenna is wideband (impedance matched within the band 19-31 GHz, i.e., ∼ 50%) and provides multi-beam radiation for polar angles as far as ±22.5 • . The peak value of the gain is 19.7 dBi and the maximum radiation efficiency equals 50%. Furthermore, the antenna array is combined with a dual-band polarization converter. The latter provides orthogonal circular polarization in two non-adjacent bands. The overall antenna system performs right-and left-hand circular polarization within the SatCom down-and up-links in the K/Ka-band, respectively. For each polarization, the axial ratio is below 3 dB over 9.47% and 4.42% fractional bandwidths, respectively.

“…Hollow Wideband linear source generator (LSG) and full-corporatefeed parallel plate waveguide (PPW) power divider, as the feed network, is commonly used to support the wideband of CTS antenna. So far, the reported maximum fractional bandwidth of the CTS antenna is around 48% [36], which can not perfectly cover the aforementioned multiple bands of 5G or satellite communication. Utilizing a dual-/multi-band CTS antenna has become an alternative way.…”
