Circularly Polarized Horn Antenna 13dBi Typ. Gain, 8-18 GHz Frequency Range RM-CPHA818-13

The Circular Polarization Horn Antenna is a specialized microwave antenna that converts linearly polarized signals into circularly polarized waves through an integrated polarizer. This unique capability makes it particularly valuable in applications where signal polarization stability is critical.

Key Technical Features:

• Circular Polarization Generation: Utilizes dielectric or metallic polarizers to create RHCP/LHCP signals

• Low Axial Ratio: Typically <3 dB, ensuring high polarization purity

• Broadband Operation: Generally covers 1.5:1 frequency ratio bandwidths

• Stable Phase Center: Maintains consistent radiation characteristics across frequency band

• High Isolation: Between orthogonal polarization components (>20 dB)

Primary Applications:

1. Satellite communication systems (overcoming Faraday rotation effect)

2. GPS and navigation receivers

3. Radar systems for weather and military applications

4. Radio astronomy and scientific research

5. UAV and mobile communication links

The antenna’s ability to maintain signal integrity regardless of orientation changes between transmitter and receiver makes it indispensable for satellite and mobile communications, where signal polarization mismatch can cause significant degradation.
