Abstract :
A novel circularly polarized microstrip antenna using dual-feed orthogonal and with front-end parasitic method is proposed in this paper. In the feeding network, a two-way circular-sector power divider is adopted to distribute the current equally to each feed. A method of moments is employed for optimizing the design and achieving a good circular polarization at the center frequency of 2.37 GHz. The simulated values shows that 3-dB axial ratio bandwidth and maximum gain are about 51MHz and 6.39dBic. The narrow bandwidth and reasonable gain indicate that antenna is promising for Inter Satellite Link in S-Band.
