Reflector antenna bf
A reflector antenna is an antenna that uses a metallic reflecting surface to form a predetermined radiation pattern. Its feed can be a dipole or a dipole array, or a horn or a horn array. Reflector antennas are classified into single-reflector antennas and dual-reflector antennas. They are commonly used in the microwave and millimeter-wave bands and have found extensive applications in satellite communications, microwave communications, radar, remote sensing, and bioelectronic technologies.
