Dual-Polarization and Low Scan-Loss Multi-Beam Lens Antenna Fed by Semicircular Parallel-Plate Horn Antenna with Separated Phase Centers
We propose a wide-angle beam-scanning multi-beam lens antenna with dual-polarization capability. Due to an astigmatism of the lens, focal points of the lens are separated in the beam-scanning plane and its orthogonal plane. This separation causes scan-loss. This issue is solved in both polarizations simultaneously by designing the semicircular wall radiuses of the horn antennas. The beam-scanning performance of the proposed antenna is evaluated by electromagnetic simulation in this paper.
