Antenna is the basis of Wireless communications. Its the key point which involves reception and transmission of data to and fro from any device used in Mobile or Wireless Communications.
In this tutorial, we will learn more about the basics of antenna system.
First of all we must understand , what antenna actually is.
In generic term we can say that an antenna is the converter between two kinds of electromagnetic waves.
cable bounded waves ⇔ free space waves
So we can say that an antenna is an electrical device that converts electric current into radio waves.
Technically speaking, antenna is a quad-pole device with the second termination connected to free space. Hope this image will make things clear for you.
To understand how antenna works , we first must know how wave propogates through the air. A wave is a permanent conversion from electrical into magnetical energy and vice versa. In this way a magnetic waves lead to an electrical wave and in same way an electrical wave leads to a magnetic wave.
There are lot of parameters related to antenna system, which we cover in later part of series.
