Circularly Polarized Horn Antenna 18dBi Typ. Gain, 22-32 GHz Frequency Range RM-CPHA2332-18

Short Description:

RF MISO’s Model RM-CPHA2232-18 is RHCP or LHCP circularly polarized horn antenna that operates from 22 to 32 GHz. The antenna offers a typical gain of 18 dB and low VSWR 1.5 Typ. The antenna is equipped with a circular polarizer, a circular wave-guide to circular wave-guide Converter and a conical horn antenna. The gain of the antenna is uniform in the entire frequency band, the pattern is symmetrical, and the working efficiency is high. Antennas are widely used in antenna far-field testing, radio frequency radiation testing and other scenarios.

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).
