Abstract :
Active antenna load pulling effects are analysed in the presence of a partially reflecting superstrate (dielectric cover). The analytical and experimental results obtained exhibit distortion in the frequency pulling pattern of the active antenna. The results obtained can be used to design optimum cover placement or to postmanufacture tune the frequency of the active antenna module
