An offset dish antenna or off-axis dish antenna is a type of parabolic antenna. It is so called because the antenna feed is offset to the side of the reflector, in contrast to the common "front-feed" parabolic antenna where the feed antenna is suspended in front of the dish, on its axis.

Webb11 jan. 2024 · An 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. WebbThe offset fed antenna design offers several distinct advantages over its prime focus counterparts. There is no feedhorn blockage, an important consideration when the …

WebbThe offset antennas undergo a scanning loss of 1.6 dB with a peak gain of 19.7 dBi in the main beam. The 3-dB beamwidth of 9.8-11.2° is obtained in different radiation beams. The radiation patterns of the offset antennas are tilted ± 15° with respect to the focal antenna, thus giving a radiation coverage of 30°.
