What is GSM antenna?

A Global System for Mobile (GSM) antenna is a type of antenna commonly used in mobile phones and cell towers. GSM antennas can relay signals between cell towers and cell phones. Many smartphones have other antennas for additional technologies, such as wireless Internet connections.

What type of antenna is used in microwave?

horn antenna
A horn antenna or microwave horn is an antenna that consists of a flaring metal waveguide shaped like a horn to direct radio waves in a beam. Horns are widely used as antennas at UHF and microwave frequencies, above 300 MHz.

What is microwave antenna used for?

Microwave antenna is used for radiating microwave signal into space and receiving microwave signal from space. Microwave antenna acts as a transition region between free space and guiding structure like a transmission line in order to communicate between two or more locations.

Are microwave antennas still used?

Parabolic antennas are also used as radars where they transmit a narrow beam wave of radio to equipment like ships and airplanes. These are just some of the many different kinds of microwave antennas that are now used in radio, radar, and satellite communications.

What does a microwave antenna look like?

The antenna is shaped like a dish thus it is referred to as a parabolic dish or dish antenna. Also, these antennas are used as radars. They require the transmission of a narrow beam wave of radio to some equipment such as airplanes and ships.

What is the other name for microwave dish antenna?

parabolic dish
This commonly takes the form of a dish and as such, is known by its other names: dish antenna or parabolic dish. Using a parabolic reflector, which is curved in shape, allows this kind of antenna to direct radio waves.

What is the difference between terrestrial microwave and satellite microwave?

Terrestrial microwave transmissions are sent between two microwave stations on the earth (earth station). It is the most common form of long-distance communication. Satellite microwave transmissions involve sending microwave transmissions between two or more earth-based microwave stations and a satellite.

What is the difference between GPS antenna and GSM antenna?

GPS is a circularly polarized antenna for satellite communications at a frequency of 1575.42 +/-10 MHz L2: 1227.60 +/- 10 MHz. GSM is a linearly polarized antenna for mobile communications, China Mobile GSM frequency: up 890-909MHZ; down 935-954MHZ. The GPS antenna is a kind of navigation antenna.

Which antenna is used for terrestrial microwave link between cell towers?

Microwave circular horn antennas are used for terrestrial microwave link between the cell towers. The antenna can function as transmit, receive or transmit/receive both. In order to use antenna as both transmitter and receiver, duplexer is used.

What is microwave circular horn antennas?

Microwave circular horn antennas are used for terrestrial microwave link between the cell towers. The antenna can function as transmit, receive or transmit/receive both. In order to use antenna as both transmitter and receiver, duplexer is used. There should be 10*λ distance between the two transmit or receive antennas.

What are microwave antennas used for?

In special applications, the antennas can be used to accommodate a specific down tilt to achieve a near field coverage. Some microwave antenna designs are available in a wide range of frequency gains and bands. 7. Tracking Antenna These designs are made specifically to stabilize and align the antenna automatically.
