The objective of this study is the design and implementation of a Quadrifilar Helix Antenna (QHA) for telemetry, tracking and control of a Low Earth Orbit (LEO) satellite. Because of its cardioid-shaped circularly polarized beam, QHA can satisfy requirements of satellite communications completely. In this paper, a variation of QHA referred to as “self-phased QHA” with a single feeding circuit, has been proposed to reduce implementation complexity. The designed antenna has been analyzed and the experimental results show that the radiation pattern provides good wide-beam in the desired frequency while the antenna’s bandwidth is around 200MHz when VSWR is less than 2. Keywords: quadrifilar helix antenna, circular polarization, satellite communication
*A self phased antenna element with two pairs of arms (110, 120, 130, 140) in a crossed relationship transceives a signal at a resonant frequency. A dielectric (150, 160) is disposed adjacent an arm (130, 140) to obtain a self phased relationship in the arms (110, 120, 130, 140) at the resonant frequency. The arms can form crossed loops or twisted crossed loops such as a quadrifilar helix.
*A quadrifilar helix antenna (QHA) operating at 0.94GHz is designed and realized in this paper. The designed QHA consists of four helical conductors which are excited in phase quadrature by employing a Wilkinson divider which shows good performance in return loss and transmission characteristic. According to the designed parameters of the helices and Wilkinson divider, a QHA is fabricated.
*A self-phased quadrifilar helix antenna is designed, simulated, fabricated and measured for use in Army air-to-ground and airborne-assisted ground-to-ground communication systems. The effect of the metallic ground plane provided by the aircraft fuselage is explored through simulation, and the ideal standoff distance from this ground plane to maximize realized gain is determined.
