Antenna is a common term that we all have heard many times. It is used in several devices at commercial and residential places. Antenna helps to change electric power into electromagnetic waves.

In this article, we will cover the meaning of antenna, functions of antenna, benefits, and kinds of antennas. We will also discuss many other things related to antenna.

What is an Antenna?

Before we discuss the benefits and functions of the antenna, let us know the meaning of the antenna. It is a metallic tool that helps to send radio EM waves. The antenna is used either as a receiving antenna or transmitting antenna.

Antennas can be used in various electronic systems that need signal transmission. They work with radio waves that pass from one point to another.

Basic Function of the Antenna

Now, let us have a look at how the antennas work. To understand the working of an antenna, it is necessary to know the parts of an antenna. It is a kind of metal device that transmits radio frequency waves from one point to another in space.

A high voltage in a transmitting antenna produces radio signals that travel to a receiving antenna. In this antenna, the signal is turned again into electrical energy. Some of the main characteristics of an antenna are:

• Radiation patterns

Radiation pattern of the antenna is shown with the help of quantity Field Strength. Antenna emits radio waves only in one direction while the energy sent in other areas is negligible.

• Radiation intensity

Radiation intensity of an antenna is measured as the radiated power to input power. Efficiency of an antenna depends on the quality of materials used in making it. The quality of materials affects the performance of an antenna.

• Bandwidth

Antennas work under different frequencies. Bandwidth of antenna is the fixed set of frequencies at which aerial characteristics are maintained under a certain value. 

• Input impedance

Input impedance of an antenna is the amount of opposition mounted against the current flow via its conductive materials. Antenna will only work effectively when there is sufficient input impedance to its input transmission line.

• Polarization

The direction in which the electromagnetic waves are emitted in antenna is polarization. In the case of antenna that emits radio waves in different directions, the direction of maximum gain is used to show polarization.

• Aperture

Aperture is the terms used in a receiving antenna. Aperture in an antenna is the ability of an antenna to produce relevant signals from electromagnetic waves.

Why do we need Antennas?

Antennas are used in various electronic systems such as radio and TV. They are used for various tasks such as transmitting and broadcasting. Apart from that, the antennas also give many other benefits such as:

1. Increases range of operation

One of the major benefits of using an antenna in any device is that it increases the range of operation. It also improves the quality of communication and helps network providers to provide the coverage at low cost.

2. Increases number of users on the same frequency

Antennas will increase the number of users on the same frequencies. More users will decrease the operating costs of network providers. Antenna is a cost-effective tool to provide more coverage at low costs.

3. Increases the bandwidth

Antenna increases bandwidth in the frequencies. It also strengthens the signals to reach the device and improves performance as well.

Smart Antenna is an important accessory to use for precise communication. It works with the help of digital signal processing algorithms. This antenna is used in many wireless communication devices and reduces errors while communicating with each other. Besides, the smart antenna also boosts the speed of data between the sources and destination.

We will discuss everything related to Smart Antennas in this blog with its features, benefits, and the process of working. You will get a better idea of the smart antenna by reading this blog.

What is a Smart Antenna?

We discussed some lines on a smart antenna in the above section. Now, let us discuss more on this antenna with an explanation. A smart antenna is a kind of digital antenna that can track signals. It is used for various purposes such as telecommunications, radar, and signal processing.

Another name for a smart antenna is an adaptive array antenna. It is widely used in many applications such as wireless devices and reconfigurable broadband devices.

Functions of a Smart Antenna

Smart Antenna has 2 functions namely Estimation of Direction of arrival and Beamforming method. Let us discuss both the functions in detail:

1. 1.     Estimation of Direction of arrival

Different techniques help to find the DOA of a signal in a smart antenna. You have to do a lot of algorithms and computations to find DOA. The matrix Pencil method is a very common method to find the direction of arrival.

1. 2.     Beamforming method

In the beamforming method, the signals are sent to the smart antenna directionally. This method enhances the quality of signals that are transmitted to the smart antennas. Besides, this method also increases throughput and you can use various common antennas.

Different kinds of smart antennas

A smart antenna can be UHF Antenna and other kinds. It can be classified according to the kind of environment and system requirements. Now, let us discuss the different types of smart antennas in detail below:

1. 1.     Adaptive Array Antenna

In this antenna, there is a change in beam pattern due to the movement of the interference and the movement of the wanted user. All the signals received will be combined to increase the wanted signal to interference.

The smart antenna can bring the main beam in any one direction and eliminate the interfering signal. DOA method is used to calculate the direction of the beam.

1. 2.     Phased array or multi-beam antenna

This is another type of VHF Antenna in which there are multiple fixed beams in which only one beam will turn on and send the wanted signal. You have to do adjustments in the phase to do the required settings.

Benefits of using a smart antenna

A smart antenna has many nice features that help to improve signals during communication. It has several benefits such as:

• Better range

One will get a better range of operation in a smart antenna. This is because the smart antenna focuses on communicating devices. After installing this Log Periodic Dipole Antenna, the network providers can save costs. They will not have to use several antennas to get coverage.

• Less interference in the performance

Interference is often caused by transmissions that go in all directions. But in the case of a smart antenna, the directionality is caused by the antenna. Due to this pattern, you will get a better range and ability to use frequencies. You will get the proper communication pattern after using a smart antenna in any device.

• Multiple users

Yagi Antenna is a very commonly used antenna these days. The targeted nature of smart antenna frequencies gives comfort to multiple users to use this antenna. If the number of users increases, there is a reduction in the operating costs of a network provider. Using a directional antenna will help to decrease operational costs.

• Increases security

A smart antenna works differently from an Omni antenna. It radiates signals only in one signal and not in several directions like in the case of the Omni quadrifilar helix antenna. It means a person has to be in the same location to get better transmissions between two devices after using an antenna.

• Gives better coverage in the medium and long-distance areas

Smart antennas are widely used in complex wireless environments with different obstacles. They will enhance communication in areas with obstacles such as high and thick walls, partitions, meeting rooms, and penetrating surfaces. These antennas will give better coverage in such areas where communication is not possible.

Final words

We discussed many things about circular polarized high gain helical antenna and its features with benefits. A smart antenna can easily pass through obstacles and hurdles of a building and give better communication lines to multiple users at a time. It is one of the best antennas to be used in modern wireless communication services.
