Parabolic antenna - Wikipedia
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 .
What are Parabolic Antennas? - everything RF
2024年6月4日 · A parabolic antenna (or a dish antenna) is a type of directional, high-gain antenna characterized by a parabolic reflector. It consists of two main parts: a parabolic dish/reflector and the feed antenna located in the middle of the parabolic dish.

A type of reflector which has a reflecting surface having the shape of a paraboloid that is used to collect and re-radiated the electromagnetic energy is known as Parabolic Reflector. It is regarded as the simplest and popular form of reflector antenna.
The Parabolic Reflector Antenna (Satellite Dish) - Antenna Theory
The most well-known reflector antenna is the parabolic reflector antenna, commonly known as a satellite dish antenna. Examples of this dish antenna are shown in the following Figures. Figure 1. The "big dish" antenna of Stanford University. Figure 2. A random direcTV dish antenna on a roof.
Parabolic Antenna | Properties | Feed mechanisms | Parabolic ...
The Parabolic Antenna is a plane curve, defined as the locus of a point which moves so that its distance from another point (called the focus) plus its distance from a straight line (directrix) is constant. These geometric properties yield an excellent microwave or light reflector, as will be seen. Geometry of the parabola:

Everything You Need to Know About Parabolic Reflector Antenna
What is Parabolic Reflector Antenna? The theory of parabolic antenna comes from the basic curve of parabola, which is two-dimensional. When this shape is transformed into a three-dimensional, the spherical wave-like structure turns into a shape known as a paraboloid.
