Abstract
An antenna device including matching circuits corresponding to reflection coefficients of antenna elements determined by taking into account the couplings between the antenna elements occurring when the antenna elements are excited with corresponding excitation amplitudes and excitation phases at each of operational frequencies.
Claims6
An antenna device comprising a plurality of antenna elements operated at a plurality of frequencies, a divider/combiner circuit for exciting said plurality of antenna elements at desired phases, and matching circuits each connected to said antenna element at one end and connected to said divider/combiner circuit at the other end, said matching circuits corresponding to reflection coefficients of said antenna elements determined by taking into account the coupling between said antenna elements occurring when said antenna elements are excited with corresponding excitation amplitudes and excitation phases at each of said frequencies.
