An improved tunable antenna of planar construction is distinguished by the following features: in plan view perpendicular to the effective surface ( 7 ), the electrically conductive structure ( 13, 113 ) completely or partially covers the effective surface ( 7 ), the electrically conductive structure ( 13, 113 ) is coupled and/or connected galvanically or capacitively or serially and/or with interposition with at least one electrical component ( 125 ) with the ground surface ( 3 ) and/or a chassis (B) located on a potential or ground.
