Abstract
A wireless communication device includes: an antenna including an antenna element, and a ground conductor; an IC connected to the antenna; and a metal member arranged to face the antenna. The ground conductor includes one end and the other end in the X direction. The metal member includes a metal plate, and a projection protruding from the metal plate toward the antenna. The projection is arranged at a position of overlapping with the end of the ground conductor as viewed in the −Z direction. Such a configuration improves the transmission and reception gains at the communication frequency of a radio element.
Claims17
A wireless communication device comprising:
- an antenna that includes
- an antenna element whose one end is open, and
- a ground conductor to which another end of the antenna element is connected and which is used as a ground;
- a metal member arranged to face the antenna;
- and
- a radio element connected to the antenna,
- wherein the ground conductor includes a first end located on a side of the open one end of the antenna element, and a second end located on a side opposite to the open one end of the antenna element, and
- wherein the metal member includes
- a metal main body, and
- a projection that projects from the metal main body toward the antenna, in at least one region between a first region facing the first end of the metal member and a second region facing the second end.
10-16. (canceled)
A wireless communication device comprising:
- an antenna that includes
- an antenna element whose one end is open, and
- a ground conductor to which another end of the antenna element is connected and which is used as a ground;
- a metal member arranged to face the antenna;
- a radio element connected to the antenna;
- and
- a conductor piece that is provided so as to cover a region including a site on the ground conductor at which a ratio of an electric field intensity to a magnetic field intensity is a maximum and which has a surface area larger than an area of the region.
