An antenna is an electrical device which converts electric energy into radio waves, and vice versa. It is usually used with a radio transmitter or radio receiver. An antenna is a device for sending or receiving electromagnetic waves. A device that converts sound, light, or electrical signals into radio, microwave, or other electrical signals . An antenna used to convert electromagnetic waves in to electrical energy. LOG – PERIODIC ANTENNA YAGI – UDA ANTENNA HELIX ANTENNA PARABOLIC ANTENNA LOOP ANTENNA A unidirectional antenna in which the length and spacing of the elements increase logarithmically from one end to the other. It is frequency-independent antenna. Frequency range – VHF and UHF band. It is broadband antenna. It is unidirectional antenna. It is frequency independent antenna. A directional-type antenna consisting of one or more complete turns of a conductor. It determine the direction of arrival of radio signals. Frequency range – 500-1600KHz.

3. Antenna
An antenna is an electrical device which converts
electric energy into radio waves, and vice versa. It is
usually used with a radio transmitter or radio
receiver.
An antenna is a device for sending or receiving
electromagnetic waves.

4. TRANSMITTER ANTENNA
A device that converts sound,
light, or electrical signals
into radio, microwave, or
other electrical signals .

5. RECIVER ANTENNA
• An antenna used to convert electromagnetic
waves in to electrical energy.

6. TYPES OF ANTENNA
 LOG – PERIODIC ANTENNA
YAGI – UDAANTENNA
HELIX ANTENNA
 PARABOLIC ANTENNA
 LOOP ANTENNA

7. Log - periodic antenna
 A unidirectional antenna in which the length and spacing of
the elements increase logarithmically from one end to the
other.
 It is frequency-independent antenna.
 Frequency range – VHF and UHF band.

8. Log - periodic antenna

9. Advantages
It is broadband antenna.
It is unidirectional antenna.
 It is frequency independent antenna.

10. LOOP ANTENNA
A directional-type antenna consisting of one
or more complete turns of a conductor.
 It determine the direction of arrival of radio
signals.
 Frequency range – 500-1600KHz.

11. LOOP ANTENNA

12. Application
Direction finding of signal propagation.
 Radio(AM/FM)reception.
 Long distance point to point communication.

13. CONCLUSION
All the antenna are very useful in all the
application such as transmitter and receiver.
Antenna are used to convert electrical energy
to electromagnetic energy
