A planar spiral antenna is an antenna used for transmitting and receiving rotating polarized electromagnetic signals in space, with the following characteristics and applications.
1. Polarization mode: Planar spiral antenna has a left-handed polarization mode or a right-handed polarization mode.
2. Impedance matching: Planar spiral antenna has good impedance matching performance.
3. Radiation direction: Antenna has good radiation direction performance, with the maximum radiation direction being in the normal direction on both sides of the plane and radiating circularly polarized waves.
4. Non frequency dependent characteristics: such as equiangular spiral antennas, whose shape is determined by angle and does not include linear length, their characteristics are not affected by frequency changes, and they have an extremely wide frequency band.
1. Reconnaissance orientation: Due to the left-handed or right-handed polarization mode and good radiation directional performance, horn antenna can accurately receive electromagnetic signals in specific directions and polarizations for reconnaissance of target orientation and signal sources.
2. Satellite communication: RF horn antenna can be used as a feed source for reflector satellites, efficiently feeding the received weak satellite signals to the receiving equipment.
3. Other fields: Microwave horn antenna also has applications in ultra wideband communication systems, military radar, biotechnology, and other fields, such as avoiding interference between ultra wideband communication and narrowband communication systems.
Qualwave supplies planar spiral antennas cover the frequency range up to 40GHz. We offer standard gain horn antennas of the gain 5dB, as well as customized dual polarized horn antennas according to customers requirements.
