Abstract:
1. An antenna device comprising: a mother substrate including a feed line and a ground; and a chip antenna mounted on the mother substrate, the chip antenna including: wherein the coupling adjusting conductor plate covers a center part of an area where the parasitic conductor element and the radiating conductor element overlap each other when viewed in a thickness direction of the laminated body, and straddles the radiating conductor element in a direction orthogonal to a direction of a current that flows in the radiating conductor element, a front-side ground conductor plate connected to the ground is provided on a front side of the mother substrate, wherein the front-side ground conductor plate includes a connecting aperture larger than the radiating conductor element, the radiating conductor element is connected to the feed line of the mother substrate at the position of the connecting aperture via the first flat electrode pad of the land grid array, and both end sides of the coupling adjusting conductor plate are connected to the front-side ground conductor plate of the mother substrate via the second flat electrode pad and the third flat electrode pad of the land grid array.
