a Under the RHCP incidence, two main output lobes located at −16° and 58° carry co-polarization and cross-polarization respectively. b Under the RHEP incidence, four lobes appears at −35°, −16°, 0°, and 58° for L–L, R–R, L–R, and R–L channels respectively. c Under the LP incidence, four lobes are exhibited at −35°, −16°, 0°, and 58°. d Under the LHEP incidence, four lobes are shown at −35°, −16°, 0°, and 58°, which is opposite to that of RHEP incidence. e Under the LHCP incidence, only two main output lobes located at −35° and 0° carry co-polarization and cross-polarization, respectively.
