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