Reflector Antennas
Reflector antennas are a type of antenna that use a reflective surface to direct radio waves, enhancing signal strength and directivity. Reflector antennas are ideal for applications such as satellite communications, radio telescopes, and radar systems.

Design and Analyze Parabolic-Reflector-Backed Wideband Egg Crate Array
Create an egg crate array of vivaldiOffsetCavity antenna elements backed by a parabolic reflector. The Vivaldi antenna is widely used in radar and electronic countermeasures because of its simple structure and wide operating bandwidth. The egg crate array consists of Vivaldi antenna elements oriented in a grid. The egg crate array in Antenna Toolbox™ is a fully metallic array, which is capable of handling a high average power. Vivaldi phased arrays are used for a wide range of applications at various frequencies and bandwidths. The egg crate array of vivaldi antenna elements provides a wide bandwidth. You can back the array with any Antenna Toolbox backing structure. In this example, you analyze the Vivaldi element, egg crate array, and egg crate array backed with a parabolic reflector over 5G frequency bands.
Design and Analyze Curved Reflector Antennas
Design and analyze the curved reflector antennas. Curved reflector antennas are an upgraded version of rectangular reflector antennas. The curved reflector surface of these antennas reflects and focuses the signal, thereby increasing the signal strength. Some of the notable characteristics of the curved reflectors are high gain, low cross-polarization, and reasonable bandwidth.
Design and Analyze Cassegrain Antenna
Design and analyze a cassegrain antenna.
Reflector Backed Equiangular Spiral
The spiral antenna is an inherently broadband, and bidirectional radiator. This example will analyze the behavior of an equiangular spiral antenna backed by a reflector [1]. The spiral and the reflector are Perfect Electric Conductors (PEC).
