Abstract (en)
To enable a billboard to double as a film antenna, advertising characters 11a, 11b forming an advertising image are constituted by metal wire which defines the outer edges of the characters, and the advertising characters 11a, 11b are connected to each other by metal wire. A cold side antenna element 12 is formed on the film substrate 10 from metal wire around the advertising characters 11a, 11b and the outer periphery of the film substrate 10. The connected advertising characters 11a, 11b form a hot side antenna element 13, thus enabling the billboard 1 to operate as a film antenna. <IMAGE>
