Plane antenna

Abstract

Abstract PURPOSE:To improve the antenna efficiency and to miniaturize the titled antenna by laminating a feeding circuit board and a radiation circuit board via a supporting board in common use of a dielectric layer and containing the lamination block into a box whose face corresponding to the radiation circuit pattern is made of a radome member. CONSTITUTION:The lamination block where a ground conductor board 1, the feeding circuit board 3 formed with a feeding line 2 on an insulation film 2a and the radiation circuit board 5 formed with the radiation circuit pattern 4 on an insulation film 4a are laminated through supporting boards 6a, 6b in common use of the dielectric layer and made of a resin foamed substance, is formed. Then the block 7 is contained in the box 8 without any gap and the face of the box 8 corresponding at least to the radiation circuit pattern is made of a radome member transmitting a radio wave. Since the lamination block is contained in the box in this way, the antenna efficiency is high, the weight is light and the assembling is easy. Moreover, a hole 9 is provided to the supporting board to reduce the feeding loss.
