PROBLEM TO BE SOLVED: To solve the problem that a conventionally well-known diversity antenna capable of easily selecting the orientation of maximum sensitivity by changing directivity to an arbitrary direction is hardly installed on a thin television set because of an installation space, and if it is forcibly installed, the antenna is protruded from the top surface of the receiver and the simple external appearance of the thin television set may be impaired. SOLUTION: By using, for example, comb-like members of a supporting body for supporting the television receiver from a lower direction, an array antenna comprising: at least one parasitic antenna element switching characteristic between reflection and waveguiding by a control signal supplied from the outside; and a feeding element arranged in parallel thereto, is installed in a horizontal state.
