WINDOW GLASS FOR AUTOMOBILE WITH ANTENNA ELEMENT

摘要

PURPOSE:To improve the sensitivity of an antenna pattern of side feeding type and to obtain an excellent frequency characteristic by providing a couple of auxiliary elements on and under a lead wire leading a reception output to a feeding point. CONSTITUTION:The reception output is led to a feeding section 6 provided to the side of a window glass 1 via a lead wire 5c prolonged from the center of the antenna pattern to the side. The auxiliary elements 10a, 10b are provided along almost the entire length of the upper and lower side of the wire 5c. One end of the auxiliary elements 10a, 10b is connected to a bus 3 of a heating conductor wire group 2. Thus, the reduction in the sensitivity by the addition of the lead wire 5c is corrected and the fluctuation of the reception level is decreased. Thus, the sensitivity of the side feeding type antenna pattern is improved in this way and an excellent frequency characteristic is obtained.
