Right hand circular polarization of a quadrifilar helical antenna for satellite and mobile communication systems

Quadrifilar helical antenna is one of the most commonly used antenna for satellite and mobile phone systems. It provides high gain, shaped beam with excellent circular polarization over a wide angular range. The quadrifilar helices have the small size and weight. The proposed antenna providing a good axial ratio with low return loss. The antenna provides a very high beam width of 127° to provide a good coverage of upper hemisphere in vehicle plane and omni directional pattern in the horizontal plane. The proposed technique providing good axial ratio and low return loss.
