Parabolic reflector antenna pattern

WebAug 7, 2024 · Simplified architecture of reflector antenna (a) and desired radiation patterns along two principal cuts for radiation pattern synthesis to shape reflector's surface (b). In (c), initial radiation pattern of a parabolic reflector antenna is displayed to justify the required size of reflector, where θ x ≡ θ cos ϕ and θ y ≡ θ sin ϕ. WebThe symmetric parabolic reflector also commonly referred to as a 'dish' is a simple and widely used high gain antenna. These antennas are commonly used for satellite communications, in both civilian and military applications. The high gain of these antennas is achieved due to the electrical size of the antenna, also referred to as the aperture.
