WebAn offset-feed dish antenna has a reflector which is a section of a normal parabolic reflector, as shown in Figure 5-1. If the section does not include the center of the dish, then none of the radiated beam is blocked by the feed antenna and support structure. Otherwise, only a small bit at the edge of the beam is blocked. For small dishes, feed WebNov 22, 2024 · The concept of using parabolic satellite antennas to reflect radio waves was taken from the tradition of focusing light into a beam by using a mirror. That technology has been around since antiquity, and simply needed to be re-purposed to fit modern needs. In fact, antennas were instrumental in proving the very existence of radio waves.
