Reflector (antenna)
An antenna reflector is a device that reflects electromagnetic waves.
It is often a part of an antenna assembly.
The most common reflector types are
- a passive element slightly longer than and located behind a radiating dipole element that absorbs and re-radiates the signal in a directional way as in a Yagi antenna array.
- corner reflector which reflects the incoming signal back to the direction it came from
- parabolic reflector which focuses a beam signal into one point, or directs a radiating signal into a beam
- flat reflector which just reflects the signal like a mirror and is often used as a passive repeater
