ANTENNA DEVICE, WIRELESS COMMUNICATION DEVICE, AND ELECTRONIC DEVICE

摘要

An antenna apparatus includes a dielectric substrate, a feed element, a front array, and side arrays. The feed element, front array, and side arrays are formed on the dielectric substrate. The antenna apparatus includes mounting pads on the dielectric substrate, for coupling the antenna apparatus to another substrate by means of soldering. A part of the mounting pads are formed in a region located in a first direction when viewed from the feed element and front array, with a part of parasitic elements of the side arrays being interposed between these mounting pads and the feed element and front array. The other part of the mounting pads are formed in a region in a second direction when viewed from the feed element and front array, with another part of the parasitic elements of the side arrays being interposed between these mounting pads and the feed element and front array.

1. An antenna apparatus comprising:
a dielectric substrate; a front array including:
a feed element formed on the dielectric substrate and offering one radiation direction; anda plurality of parasitic elements formed, on the dielectric substrate, in a region located in the radiation direction when viewed from the feed element, wherein the plurality of the parasitic elements configures a plurality of front sub-arrays such that each of the front sub-arrays includes a plurality of the parasitic elements arrayed along the radiation direction, and wherein the front sub-arrays are disposed in parallel with each other along the radiation direction such that, in any adjacent two of the front sub-arrays, each of the parasitic elements of one of the two is close to a corresponding one of the parasitic elements of the other of the two; a first side array including
a plurality of parasitic elements formed, on the dielectric substrate, in a region located in a first direction orthogonal to the radiation direction when viewed from the feed element and the front array, the plurality of the parasitic elements of the first side array being arrayed substantially along the radiation direction; a second side array including
a plurality of parasitic elements formed, on the dielectric substrate, in a region located in a second direction opposite to the first direction when viewed from the feed element and the front array, the plurality of the parasitic elements of the second side array being arrayed substantially along the radiation direction; at least one first mounting pad disposed, on the dielectric substrate, in a region located in the first direction when viewed from the feed element and the front array, for coupling the antenna apparatus to a different substrate by soldering; and at least one second mounting pad disposed, on the dielectric substrate, in a region located in the second direction when viewed from the feed element and the front array, for coupling the antenna apparatus to the different substrate by soldering, wherein a part of the plurality of the parasitic elements of the first side array is disposed between the first mounting pad and both the feed element and the front array, and a part of the plurality of the parasitic elements of the second side array is disposed between the second mounting pad and both the feed element and the front array.
