Abstract
An antenna device includes a dielectric substrate and a plurality of radiating elements that each have a flat profile. A groove, continuous or segmented, is formed in the dielectric substrate to surround the radiating element in plan view. Another groove, continuous or segmented, is formed around another radiating element. The radiating element and the another radiating element are adjacent to one another.
Claims17
A communication device comprising:
- an antenna device including:
- a dielectric substrate;
- and
- a plurality of radiating elements that each have a flat profile and are supported by the dielectric substrate, wherein
- the dielectric substrate includes a first groove formed therein that, in a plan view, surrounds a radiating element among the plurality of radiating elements, the first groove being continuous or segmented with breaks between segments, and
- the dielectric substrate includes one or more additional grooves formed therein that respectively surround remaining radiating elements of the plurality of radiating elements, the one or more additional grooves each being continuous or segmented with breaks between segments, the one or more additional grooves being separate from the first groove,
- wherein each of the plurality of radiating elements are surrounded by a single groove;
- and
- a supporting member to which the antenna device attaches, the supporting member including a convex portion formed as a fence having a shape and width that matches the first groove and the one or more additional grooves such that the convex portion is received in the first groove and the one or more additional grooves.

A communication device, comprising
- an antenna device including:
- a dielectric substrate;
- and
- a plurality of radiating elements that each have a flat profile and are supported by the dielectric substrate, wherein
- the dielectric substrate includes a first groove formed therein that, in a plan view, surrounds a radiating element among the plurality of radiating elements, the first groove being continuous or segmented with breaks between segments,
- the dielectric substrate includes a second groove formed therein that surrounds another radiating element of the plurality of radiating elements, the first groove and the second groove having a shared portion between the radiating element and the another radiating element, and
- the radiating element and the another radiating element being adjacent to one another;
- and
- a supporting member to which the antenna device attaches, the supporting member including a convex portion formed as a fence having a shape and width that matches the first groove and the second groove such that the convex portion is received in the first groove and the second groove.

A communication device, comprising:
- an antenna device including:
- a dielectric substrate;
- and
- a plurality of radiating elements that each have a flat profile and are supported by the dielectric substrate, wherein
- the dielectric substrate includes a groove formed therein that, in plan view, has a lattice shape, and
- respective of the plurality of radiating elements are disposed in separate regions that is partitioned from one another by the groove formed in the lattice shape;
- and
- a supporting member to which the antenna device attaches, the supporting member including a convex portion formed as a fence having a shape and width that matches the groove formed in the lattice shape.
