    (54) Phase control microstripline antenna


    (57) A phase control microstripline antenna (10, 10a, 10e, 10f) comprises a dielectric substrate (11), singular or plural strip conductors being bent periodically and a ground conductor (13). A single or a plurality of resonance elements (14, 15, 20, 21, 32, 38, 42, 49, 50, 53) for being supplied with electric current from a predetermined position of singular or plural strip conductors (12, 30, 31, 40, 41) in every period of the strip conductors (12, 30, 31, 40, 41) are disposed to control phase of electric wave being radiated from the strip conductors (12, 30, 31, 40, 41).
