Abstract

PURPOSE:To improve the directivity in the very high frequency band by making connections while electric power induced at a very high frequency antenna is made in phase with that at a heating conductor, by adjusting the length of the antenna by shifting the position of the open end of the antenna. CONSTITUTION:Between common current collecting line 10 at one lateral side of transparent plate glass 1 and buses 11 and 11a at the opposite side, heating conductor groups 13 and 13a of heating conductor elements 12 are extended. On the surface of glass 1 at the upper parts of conductor groups 13 and 13a, very high frequency antenna element 21 made of conductor 16 connecting with feeding terminal 14 is arranged being folded at channel-shaped part 22 in parallel to element 12. Tip 23 of antenna element 21 is made open and folded upward in the same direction with channel-shaped part 22 to adjust its length and intermediate connection part 24 on the lower straight line of antenna element 21 and connection part 25 of conductor group 13 at the uppermost part are connected together via lead wire 31. Then, electric power induced at antenna element 21 is made in phase with that at antenna element 21 to improve the directivity in the very high frequency range, improving the SN ratio.
