The Dual Circular Polarized Horn Antenna is a sophisticated microwave component capable of simultaneously transmitting and/or receiving both Left-Hand and Right-Hand Circular Polarized waves. This advanced antenna integrates a circular polarizer with an Orthogonal Mode Transducer within a precisely engineered horn structure, enabling independent operation in two circular polarization channels across wide frequency bands.

Key Technical Features:

Dual CP Operation: Independent RHCP and LHCP ports
Low Axial Ratio: Typically <3 dB across operating band
High Port Isolation: Generally >30 dB between CP channels
Wideband Performance: Typically 1.5:1 to 2:1 frequency ratio
Stable Phase Center: Essential for precision measurement applications

Primary Applications:

Satellite communication systems
Polarimetric radar and remote sensing
GNSS and navigation applications
Antenna measurement and calibration
Scientific research requiring polarization analysis

This antenna design effectively mitigates polarization mismatch losses in satellite links and provides reliable performance in applications where signal polarization may vary due to environmental factors or platform orientation.
