Antifogging plate glass equipped with omnidirectional receiving antenna

Abstract

Abstract PURPOSE:To improve the gain for a medium wave band and eliminate directivity in a very high-frequency band, by connecting the bent type very high-frequency wave receiving antenna, which is provided outside the heating conductor, to the heating conductor directly. CONSTITUTION:Heating conductor 11 operates as a medium wave band receiving antenna exclusively. Bent antenna 15 for very high-frequency wave receiving is provided to transparent plate glass 1 in the upper part of heating conductor 11. Heating conductor 11 and very high-frequency wave receiving antenna 15 are connected in close parallel conductor parts in respect to the distributed constant. One end of very high-frequency wave band receiving antenna 15 is connected to heating conductor 11 directly. Therefore, radio waves of the medium wave band received by heating conductor 11 are transmitted to the receiver through the very high-frequency wave band receiving antenna without loss.
