WebFresnel zone antennas belong to the category of reflector and Lens antennas. Unlike traditional reflector and lens antennas, however, the focusing effect in a Fresnel zone antenna is achieved by controlling the phase shifting property of the surface and allows for flat [1] [6] or arbitrary antenna shapes. [4] When integrated into an antenna assembly, the reflector serves to modify the radiation pattern of the antenna, increasing gain in a given direction. Common integrated reflector types are • parabolic reflector, which focuses a beam signal into one point or directs a radiating signal into a beam. reddit hiphopgw
