A New Test Method for the Electrical Parameter Deviation of GPS Antenna Patches

The electrical parameter deviation of GPS antenna patch base material is caused by the productive processes, and it influences on the performance of GPS antenna. A rapid test method for the electrical parameter deviation of GPS antenna patches is proposed in this paper. The design principle and the test apparatus are given in detail based on the stripline model. The test result shows the proposed method is efficiency and the test method is also convenient for large-scale manufacture.
