What are the components of an antenna?

Among the elements we can find are horns, dipoles, helices, and spiral antennas. Phase arrays can be used for cases such as a fixed beam, either single or multiplexed; electronically steerable scanning beams; or a feed array of a lens or reflector antenna system.

What are the 3 basic types of antennas?

There are several different types of antennas in three broad categories: omni-directional, directional, and semi-directional.

What is the working principle of antenna?

1) Electricity flowing into the transmitter antenna makes electrons vibrate up and down it, producing radio waves. 2) The radio waves travel through the air at the speed of light. 3) When the waves arrive at the receiver antenna, they make electrons vibrate inside it.
