1. Antenna
An antenna is a transducer that converts radio frequency electric current to electromagnetic waves that are then radiated into space. The electric field or "E" plane determines the polarization or orientation of the radio wave.

2. Definition
It is the polarization of the wave radiated by the antenna in the far field.
The polarization of each antenna in a system should be properly aligned. Maximum signal strength between stations occurs when both stations are using identical polarization.
Direction of antenna & Polarization is alike

3. Types of Polarization
Linear
Vertical
Horizontal
Circular
Elliptical

4. Types of polarization Linear Polarization Circular Polarization
Elliptical Polarization
Vertical Polarization
Horizontal Polarization

5. Match the Applications
TV Broadcasting - Linear Polarization
FM Radio - Horizontal polarization
Blue sky - Circular Polarization

6. Polarization Mismatch
The polarization of the receiving antenna is not same as the polarization of the incident wave. This is called as “Polarization Mismatch”.

7. Polarization Loss Factor
Electric field of the incoming wave
Electric field of the receiving antenna
