What Is The Function Of Antenna?

What antenna means?

1 plural antennae : one of a pair of slender, movable, segmented sensory organs on the head of insects, myriapods, and crustaceans — see insect illustration.

2 : a usually metallic device (such as a rod or wire) for radiating or receiving radio waves a TV antenna..

What is antenna and its application?

An antenna is mainly used as a metallic device for radiating or receiving radio waves which is basically used for transmitting signals, transmitting antenna is used to transmit information and for receiving signal, receiving antenna is used at receiver end to receive signals.

How many types of antenna are there?

There are several different types of antennas in three broad categories: omni-directional, directional, and semi-directional. – Omni-directional antennas propagate in all directions. – Semi-directional antennas propagate in a constricted fashion, defined by a specific angle.

What makes a good antenna?

With copper being twice as conductive as aluminum and 6 times more conductive than steel, it makes an excellent choice as an antenna material. The increased electrical efficiency means more of your RF energy will go up and out the antenna and not be trapped, creating heat energy.

What are the characteristics of antenna?

Certain basic characteristics of antenna are listed below:Antenna Radiation Pattern.Radiation Intensity.Directivity and Gain.Radiation Efficiency and Power Gain.Input Impedance.Effective Length.Bandwidth.Effective Aperture.More items…•

What is the main function of antenna?

“The two functions of an antenna are: (1) For transmission of a signal, radiofrequency electrical energy from the transmitter is converted into electromagnetic energy by the antenna and radiated into the surrounding environment (atmosphere, space, water); (2) for reception of a signal, electromagnetic energy impinging …

How does a antenna work?

How does an antenna work? The antenna at the transmitter generates the radio wave. … The voltage across the antenna elements and the current through them create the electric and magnetic waves, respectively. At the receiver, the electromagnetic wave passing over the antenna induces a small voltage.

What is the role of antenna in communication?

Antennas are a very important component of communication systems. By definition, an antenna is a device used to transform an RF signal, traveling on a conductor, into an electromagnetic wave in free space. … When a signal is fed into an antenna, the antenna will emit radiation distributed in space in a certain way.

What is antenna and its types?

The dipole, monopole, array and large loop antenna types below typically function as resonant antennas; waves of current and voltage bounce back and forth between the ends, creating standing waves along the elements. … Aperture antennas can be resonant or not.

What are three types of antenna types?

3.3. Types of Antennas. There are three main antenna categories available for wireless LANs: Omnidirectional, Semidirectional and Highly directional. Omnidirectional – Omnidirectional antennas are designed to radiate a signal in all directions.
