摘要:
A antenna device, which includes a first dielectric substrate having a patch conductor disposed thereon; a second dielectric substrate having a grounding conductor disposed on a confronting substrate surface confronting the patch conductor; and a conductor for electromagnetic coupling, extending from the confronting substrate surface of the second dielectric substrate toward the first dielectric substrate, is provided. The antenna device is small and is capable of being mounted to a windowpane for a vehicle since the conductor for electromagnetic coupling is not connected to the grounding conductor with respect to a direct current and since the conductor for electromagnetic coupling and the patch conductor are electromagnetically coupled each other.

摘要:
An antenna device of simple structure and high performance which is capable of lessening a reduction of a converging efficiency of radio wave due to a window glass sheet or the like to which the antenna device is fitted, and capable of obtaining a high converging efficiency to a received radio wave. The antenna device comprises a fitted member (5) having transparency, a converging member (1) for converging a radio wave, a space between the fitted member (5) and the converging member (1), and a receiving portion for receiving the radio wave converged by the converging member (1) or a transmitting portion for radiating a radio wave to the converging member (1) wherein in a case that a receive power value is changed so as to take alternately a bottom value and a peak value depending on a change of the thickness of the space, the thickness of the space is adjusted so that the received power value does not take a value in the vicinity of bottom values.
