There are different types of satellite antennas that are used for various purposes in satellite communication.
Some of the common types are:
- Mimo antennas: Mimo is an aerial technology and stands for multi input multi output. The way the mobile industry supports increased speed between 4G, 4G+, 4G++ & 5G is to broadcast the same signal over several radio channels. The mobile networks are splitting up the available spectrum into separate channels & broadcasting your data over several channels at the same time.
- Wire antennas: These are simple and low-cost antennas that consist of a wire or a rod that is electrically connected to a transmitter or a receiver. Wire antennas can have different shapes and sizes, such as dipoles, loops, helices, or spirals. Wire antennas are often used for low-frequency applications, such as radio broadcasting or amateur radio.
- Horn antennas: These are antennas that have a flared shape like a horn or a cone. Horn antennas are also known as aperture antennas, as they have an opening or a mouth that radiates or receives electromagnetic waves. Horn antennas can have different designs, such as pyramidal, conical, or corrugated. Horn antennas are often used for high-frequency applications, such as radar, microwave, or satellite communication.
- Reflector antennas: These are antennas that use a curved surface, such as a parabola or a sphere, to reflect and focus electromagnetic waves. Reflector antennas are also known as dish antennas, as they resemble a dish or a bowl. Reflector antennas can have different configurations, such as parabolic reflector, offset reflector, dual reflector, or shaped reflector. Reflector antennas are widely used for satellite communication, as they can provide high gain, directivity, and efficiency.
- Array antennas: These are antennas that consist of multiple elements or units that are arranged in a certain pattern, such as a line, a circle, or a grid. Array antennas can combine the signals from the individual elements to form a single beam or multiple beams of electromagnetic waves. Array antennas can have different types, such as log-periodic, Yagi-Uda, phased array, or adaptive array. Array antennas are often used for applications that require beam steering, scanning, or diversity, such as radar, radio astronomy, or cellular communication.
- Dipole antennas: These are a special type of wire antennas that consist of two identical and opposite wires or rods that are connected to a feed line. Dipole antennas are also known as Hertz antennas, as they were invented by Heinrich Hertz. Dipole antennas are the simplest and most fundamental type of antennas, as they can serve as a model or a reference for other types of antennas. Dipole antennas are often used for applications that require omnidirectional radiation, such as FM radio or TV broadcasting.
