Introduction to the antennas

Antenna:
The antenna is an electrical conductor or system of conductors. These antennas are the basic components of any electric system and are connecting links between the transmitters and free space or free space and the receiver.

Antennas are of two types:
1.Transmitting antenna
2.Receiving antenna

Note:
In two-way communication, the same antenna can be used as a transmitter and as a receiver. This type of antenna is known as a transceiver.

Functions of an Antenna:
1. It is used as a transducer.
2. It is used as an impedance matching device.
3. It is used to direct the radiated energy in desired directions and to suppress it in unwanted directions.
4. It is used to sense the presence of electromagnetic waves.
5. It is used as a temperature sensor.
