Abstract
A substrate with an antenna according to the present disclosure includes a circuit board having one main surface and the other main surface, and an antenna element mounted on the one main surface of the circuit board. When viewed from a thickness direction, an area of the one main surface of the circuit board is larger than an area of the other main surface, and the antenna element is mounted on at least a part of a region that is on the one main surface of the circuit board and that protrudes from the other main surface.
Claims18
An antenna comprising:
- a circuit board having one main surface and another main surface;
- and
- an antenna element mounted on the one main surface of the circuit board, wherein
- when viewed from a thickness direction, an area of the one main surface of the circuit board is larger than another area of the other main surface,
- the circuit board includes
- a dielectric layer configuring the one main surface, and
- a base material layer configuring the other main surface,
- the dielectric layer has a first relative dielectric constant lower than a second relative dielectric constant of the base material layer,
- the dielectric layer has
- a central portion in contact with the base material layer, and
- a peripheral portion positioned outside of the central portion, and
- a region on which the antenna element is mounted on includes the central portion and at least a part of the peripheral portion.
