A parabolic antenna is a type of antenna that uses a parabolic reflector to direct radio waves. Its shape resembles a dish, which helps focus signals to a single point, enhancing reception and transmission. These antennas are commonly used in satellite communications, television broadcasting, and radar systems. The design of a parabolic antenna allows it to efficiently collect and transmit signals over long distances. The focal point of the parabola is where the feed antenna is placed, capturing the concentrated signals. This makes parabolic antennas ideal for applications requiring high gain and precise directionality.
