Abstract
According to one embodiment, a coupler for wireless transfer includes a coupling element including a first open end and a second open end. The coupler further includes a feeding element electrically connecting a feed point and an intermediate portion of the coupling element between the first open end and the second open end. The coupler further includes a short circuiting element electrically connecting the intermediate portion and a ground plane. An electrical distance from the feed point to each of the first open end and the second open end is ¼ of a wavelength corresponding to a central frequency used for the wireless transfer.
Claims9
A coupler for wireless transfer, comprising:
- a coupling element comprising a first open end and a second open end;
- a feeding element electrically connecting a feed point and an intermediate portion of the coupling element between the first open end and the second open end;
- and
- a short circuiting element electrically connecting the intermediate portion and a ground plane,
- wherein an electrical distance from the feed point to each of the first open end and the second open end is ¼ of a wavelength corresponding to a central frequency used for the wireless transfer.
A coupler for wireless transfer, comprising:
- a substrate comprising a first surface and a second surface;
- a coupling element on the first surface of the substrate, the coupling element comprising a first open end and a second open end;
- a ground plane on the first surface of the substrate;
- a feeding element on the first surface of the substrate, electrically connecting a feed point on the first surface and an intermediate portion of the coupling element between the first open end and the second open end;
- and
- a short circuiting element on the second surface of the substrate, electrically connecting the coupling element and the ground plane, the short circuiting element comprising:
- a first end electrically connected to the intermediate portion of the coupling element via a first through-hole in the substrate;
- and
- a second end electrically connected to the ground plane via a second through-hole in the substrate.
