Abstract
Dual band, RHCP are essential to satellite receiving antenna and antenna phase center variations are a major error source of satellite navigation and positioning system, which cannot be ignored in high precision surveying applications Based on above application background, this article focuses on the analysis and the design of dual-band microstrip RHCP antenna with high stable phase center. In this study, we did research on a new design of microstrip antenna with 4 orthogonal configured probes with equal amplitude and 90° phase offset that can attain RHCP and high phase center stability and we applied stacked construction of two layers to the antenna for dual band. To satisfy the complicated feed network, we drew the feed circuit of three Wilkinson combiners in Advanced Design System and we built an HFSS design of to test and verify our overall design. As expected, simulation results show that: the antenna B1, B3 band axial ratio is less than 3dB, and the equivalent phase center deviation is less than 1mm in 60 degrees of antenna’s main beam, which satisfies the requirements in millimeter scale accuracy of satellite navigation and positioning.
