Design of helical antenna using 4NEC2

an antenna is a system of elevated conductors, which matches the receiver or transmitter to free space. Antennas are metallic structure designed for radiating and receiving electromagnetic energy. There are many types of antennas used for communication. A helical antenna is an antenna in which a conductor connected to ground plane, is wound into a helical shape. The helix is the simplest antenna which generates circular polarized waves. This paper shows using the design and simulation of helical antenna using 4NEC2 software. Gain, Efficiency, Impedance, Standing Wave Ratio (SWR) and other parameters are analyzed. Thus, a suitable helical antenna is designed and simulated which provides better radiation pattern for effective communication and for use into satellite communication.
