    • PROBLEM TO BE SOLVED: To provide an antenna device and its manufacturing method for making the body small without decreasing an antenna gain as much as possible and preventing moisture ingress inside the antenna device.
      SOLUTION: A patch conductor 12 is provided on one face of a first dielectric substrate 10, and a second dielectric substrate 14 with a grounding conductor 18 is provided opposite to this face of the first dielectric substrate 10. The first dielectric substrate 10 and the second dielectric substrate 14 are separated with a prescribed space through a lower case 16 stuck to the first dielectric substrate 10. A mixed dielectric substance 30 intervenes without a gap between the first dielectric substrate 10 and the second dielectric substrate 14, and a specific inductive capacity of the mixed dielectric substance is so determined according to the area of the grounding conductor 18 that an antenna gain becomes maximum.

    • PURPOSE:To prevent the generation of clouding by a change with the lapse of time in the above structure having a plastic film and functional film to be joined to a glass plate by providing a film having a specific energy gap between the functional film and the plastic film. CONSTITUTION:This laminated glass structure is the sandwich glass structure formed by joining, for example, a glass plate 1 on the outer side of a vehicle and glass 2 on the inner side of the vehicle via a plastic intermediate film 3 and is constituted by forming the functional film 4 on the joint surface of the glass plate 1 and the plastic intermediate film 3. The functional film 4 is exemplified by films having the optical functions to selectively reflect, shut off and transmit light of a specific wavelength region and films having the functions of electrical heating and electromagnetic shielding, etc., for thawing, defrosting, antifogging, etc. The film 8 having >=4eV energy gap is laminated on the contact surface of the multilayered films formed by crimping the functional film 4 and the metallic film 6 consisting of silver, gold, etc., by dielectric films 5, 7 consisting of ZnO, SnO2, etc. with the intermediate film 3, by which the above-mentioned structure is constituted.
