    A planar spiral antenna is an antenna used for transmitting and receiving rotating polarized electromagnetic signals in space, with the following characteristics and applications.

    Characteristic

    1. Polarization mode: It has a left-handed polarization mode or a right-handed polarization mode.
    2. Impedance matching: Has good impedance matching performance.
    3. Radiation direction: It 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.

    Application

    1. Reconnaissance orientation: Due to the left-handed or right-handed polarization mode and good radiation directional performance, it can accurately receive electromagnetic signals in specific directions and polarizations for reconnaissance of target orientation and signal sources.
    2. Satellite communication: It can be used as a feed source for reflector satellites, efficiently feeding the received weak satellite signals to the receiving equipment.
    3. Other fields: It 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.
