For the reflection coefficient testing, and then the VSWR or Return Loss of antenna, a simple testing circuit based on a directional couplers and an integrated detection chip AD8302 is introduced, which is respectively used for the sampling of forwards incident and backwards reflected wave and then the amplitude & phase detections. But due to the limited… CONTINUE READING
