Baghelani 1 Antenna 2 What is antenna Antenna i s an electrical device which converts  electric power  into  radio waves and vice versa In  transmission a radio transmitter supplies an electric current oscillating at . Typically the diameter of the ground plane should be at least 3.. λ. /4. The parameters of helical antenna are-. D- diameter of a turn on the helix antenna..
