The circularly polarized horn antenna is a specialized horn antenna that converts linearly polarized waves into circularly polarized waves by integrating a polarizer (typically designed with multi-stage dielectric phase-delay structures or helical elements). Its core performance parameters include low axial ratio (AR < 3 dB), high polarization purity, and broad bandwidth operation (typically with a 2:1 frequency ratio). This antenna effectively mitigates multipath effects and polarization mismatch losses. It offers irreplaceable advantages in applications requiring polarization stability, such as satellite communications (eliminating Faraday rotation effects), GPS navigation, radar target identification, and UAV data links, while maintaining the inherent characteristics of horn antennas, including high gain (12-25 dBi) and low voltage standing wave ratio (VSWR < 1.5).
