Double circularly polarized horn antennas typically utilize special structural designs to convert input electromagnetic wave signals into left-handed circularly polarized and right-handed circularly polarized signals. If a stepped diaphragm is installed inside a circular waveguide, a portion of the input Te10 mode is rotated 90° and converted to Te01 mode, while the phase is correspondingly delayed by 90°, forming orthogonal Te10 and Te01 modes with the same amplitude but 90° phase difference, and then synthesized into Te11 mode, achieving left-handed and right-handed circular polarization.

Characteristic

1. Good polarization characteristics: capable of transmitting and receiving left-handed and right-handed circularly polarized signals, compared to linearly polarized antennas, it has significant advantages in multi-path propagation, polarization matching, and rotational distortion in mobile communication.
2. High gain: It can concentrate electromagnetic wave energy in a specific direction for radiation, improving signal strength and transmission distance.
3. Good directionality: able to accurately control the radiation direction, allowing signals to propagate within a specific angle range, reducing signal scattering and interference.
4. High isolation: It can effectively separate left-handed and right-handed circularly polarized signals, reduce mutual interference between the two, and ensure the quality of signal transmission.
5. High power capacity: able to withstand large input power, suitable for situations where high-power signals need to be transmitted

Application

1. rSatellite communication: Used for signal transmission between satellites and ground stations, it can effectively counteract the polarization rotation and multipath effects of signals during propagation, and improve the reliability and stability of communication.
2. Radar system: It helps improve the detection and recognition ability of radar for targets, especially in complex environments, and can better receive and process the echo signals reflected by targets.
3. Radio direction finding: By receiving circularly polarized signals from different directions, the direction of the signal source is determined, and it has important applications in navigation, positioning, and other fields.
4. 5G and future communication: It can support multi-channel and multi frequency signal transmission, meet the communication needs of high bandwidth and high speed, and enhance network capacity and anti-interference ability.
