Patent attributes
An antenna apparatus includes a first dielectric substrate including a first surface and a second surface opposite to the first surface, a radiating element located on the first surface or in the first dielectric substrate, a first electrode on the second surface, a first conductor provided through the first dielectric substrate from the first surface to the second surface, to connect electrically the radiating element and the first electrode, a second dielectric substrate including a third surface and a fourth surface opposite to the third surface, an adhesive layer between the second surface and the third surface, a second electrode on the third surface, a first signal line located on the fourth surface or in the second dielectric substrate, and a second conductor provided through the second dielectric substrate from the third surface to the fourth surface, to connect electrically the second electrode and the first signal line.
