Glass antenna

Abstract

Abstract PURPOSE:To obtain characteristics similar to that of a rod antenna without forming projections by forming a pair of dipole antenna elements, the 2nd shielding lead wire holding a center lead wire between the lead wire itself and the 1st shielding lead wire and balance/unbalance converting elements branched on the way of both the shielding lead wires on the surface of glass as a pattern. CONSTITUTION:The whole dipole antenna pattern 12 is formed on the surface of the glass 10 by vapor deposition or the like. An antenna part 16 is vertically formed. A leading part 22 consists of a parallel lead wire 24 connected to the antenna elements 18, 20 and the shielding lead wire 26. The lead wire 24 is connected to the center line 28 of a coaxial feeder 14 and the lead wire 26 is connected the shielding wire 30 of the feeder 14. The shielding lead wire 32 is formed so as to hold the lead wire 24 and the lead wore is connected to the shielding wire 30. The lead wires 32, 24, 26 have a structure planing the coaxial feeder 14. The balance/unbalance conversion elements 34, 36 are upwards/downwards branched on the way of the lead wire 32 and arranged in parallel with the lead wires 32, 26. In said constitution, no projection can be attained and utility as the transmitting/receiving antenna can be attained by properly fixing the length l1 of the antenna part 16, the length l2 of the elements 34, 36 and the values of shown length l3-l5 respectively.
