How do you find the width of a parabolic cross section

Where, D = Antenna diameter length. H = Antenna dish depth. f = Focal length of the Antenna. R = Focal ratio of the antenna. A = Effective aperture of the Antenna...
The antenna dish depth is the distance from the deepest point on the surface to the chord on a perpendicular. The focal point length is the radius of the sphere with the focal point being the exact center of the sphere. The focal ratio is the focal length (sphere radius) divided by the chord (dish diameter).

  • 23/04/2012 · A parabolic antenna is an antenna that uses a parabolic reflector , a curved surface with the cross-sectional shape of a parabola , to direct the radio waves . The most common form is shaped like a dish and is popularly called a dish antenna or parabolic dish . The main advantage of a parabolic antenna is that it has high directivity . It functions similarly to a searchlight or flashlight
  • A parabolic antenna is an antenna that uses a dish that is shaped like a shallow bowl. These are used for satellite television, radio, astronomy, cellular telecommunications, and radar.
  • 2 - Find a relationship between the diameter D and the depth d so that the focal distance f is equal to twice the depth d of the parabolic dish. 3 - Find a relationship between the diameter D and the depth d so that the focal distance f is greater than d.
  • If we plot these losses 4,6 versus the energy at the edge of the dish in Figure 4-7, we find that the total efficiency of a dish antenna peaks with an illumination taper, like Figure 4-6, so that the energy at the edge is about 10 dB lower than the energy at the center.
