PURPOSE: A multiple array antenna is provided to reduce a processing time and manufacturing costs for planting by capacitively coupling a feed line to a balun(balanced-to-unbalanced transformer). CONSTITUTION: A reflective plate(100) is composed of a conductor. A first reflector(R11) and a second reflective plate(R22) are arranged on a first line(110). A first reflector(R12) and a second reflector(R21) are arranged on a second line(112). A first choke member(102) is arranged in the longitudinal direction of the reflective plate between the first line and the second line. A second choke member(104) is arranged in the direction intersecting with the first choke member. The choke member controls a beam width or changes a beam direction.
