摘要
Quadrifilar Helical Antenna is one of the most commonly used antenna for satellite and mobile phone systems. It provides a high gain, shaped beam with excellent circular polarization over a wide angular range. The Quadrifilar helix produces a cardioid shaped radiation pattern from a radiator of extremely small size and weight. The antenna provides very high beam width of 128 0 to provide a good coverage of upper hemisphere in vertical plane and omni directional pattern in the horizontal plane.
