Planar Spiral Antenna
Product Introduction
Planar spiral antennas, cylindrical spiral antennas, and conical spiral antennas have effectively solved the problem of receiving and transmitting circularly polarized signals. Among them, the AVASP series is a planar spiral antenna, which is mainly used in reconnaissance, direction finding, remote sensing and other fields.
