Abstract

An antenna device comprising: one or more substrates; a first radiating element disposed on a first region of a surface of the one or more substrates that face a cover covering the antenna device; a second radiating element disposed on a second region of the surface of the one or more substrates that face the cover; a first reflecting plate that reflects an electromagnetic wave from the first radiating element; and a second reflecting plate that reflects an electromagnetic wave from the second radiating element, wherein the first reflecting plate and the second reflecting plate take different positions in a direction perpendicular to the surface of the one or more substrates that face the cover, and the first region and the second region are regions that do not overlap each other on the surface of the one or more substrates that face the cover.

Claims (14)

1. An antenna device, comprising:

one or more substrates,

a first radiating element disposed on a first region of a surface of one or more substrates,

a second radiating element disposed on a second region of the surface of the one or more substrates,

a first reflecting plate that reflects an electromagnetic wave from the first radiating element,

a second reflecting plate that reflects an electromagnetic wave from the second radiating element, and

wherein the first reflecting plate and the second reflecting plate take different positions such that they are in different planes and positioned at different positions in relation to the one or more substrates, and the first region and the second region are regions that do not overlap each other on the surface of the one or more substrates,

wherein the one or more substrates face a cover covering the antenna device, and

wherein:

the one or more substrates include first sub-substrates including the first and second region and second sub-substrates including the second region,

the first sub-substrates include the first radiating element and the first reflecting plate,

the second sub-substrates include the second radiating element and the second reflecting plate, and

the second sub-substrates are disposed on a surface of the first sub-substrates that faces the cover.

2. The antenna device according to claim 1 , wherein the second sub-substrates are solder-mounted on the first sub-substrates.
