A quadrifilar antenna for GPS applications is designed by HFSS. This quadrifilar antenna has four helical arms wound around a dielectric cylinder which has high permittivity and low loss. The four arms are fed with equal amplitudes with 0°, 90°, 180°, 270° phase by integrated feeding network. Through precisely control of phase and design of high permittivity ceramic, quadrifilar antenna obtains proper resonant frequency and good radiation pattern. The effects including resonant frequency, axial ratio, radial pattern, impedance, gain, efficiency are simulated.
