types of microwave antennas

Microwave antennas are known for broadcasting transmissions between two or more locations, making them crucial elements for any microwave network.

They’ve been used for many years in radio and communication systems and they are becoming more significant tools in these areas as the demand for their efficiency increases.

Because of their important function, microwave antennas are designed specifically for their purpose in different systems and to meet different electrical and mechanical requirements.

Here are five of the most common types of microwave antennas and what they’re used for:

 

Horn antenna

Also known as a microwave horn, this type of antenna has a waveguide and flared end walls that form a structure resembling a megaphone, thus the name.

Horn antennas are used to transmit frequencies above 300MHz and ultra-high frequencies. They are also useful in calibrating antennas for other equipment such as automatic door openers because they have the ability to estimate the gain of other antennas near them.

 

Microstrip patch antenna

True to its name, this antenna type has a patch that radiates and connects to a ground plane on one of its parts. The microstrip patch antenna has conducting metals like gold and copper that allows it to transmit frequencies between 100MHz and 100GHz.

Microstrip patch microwave antennas can also be massed produced because of their low volume, weight and fabrication costs.

 

Omnidirectional antenna

Omnidirectional antennas transmit and receive frequencies in all equal horizontal directions, making them the perfect solutions for applications that require excellent all-around coverage. They can also be used for specific down tilt applications for near field coverage.

 

MIMO antenna

Multiple inputs and multiple outputs (MIMO) antennas are commonly used in radio transmission where they are utilized both in receiving and transmitting points to make the process of communication more efficient.

MIMO microwave antennas are some of the best in smart antenna technology because they can transmit parallel data streams and they are also useful in applications that require highly effective antenna directivity.

 

Parabolic antenna

Using a parabolic reflector, which is a curved area with a parabolic shape to direct radio waves, parabolic antennas are highly visible because of their dish shape.

These types of antennas are especially beneficial for applications that require high directivity and they are best used for point-to-point communication and in radio telescopes because of their high-end gain.

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.

They are also useful in wireless communication systems that are now being increasingly used worldwide.

Each of these antennas is designed specifically for their application and system, which is why if you’re in the broadcasting field, it’s very important to be familiar with these microwave antennas to understand where they are most efficient in broadcasting and communication systems.
