Abstract

In some examples in accordance with the present description, an electronic device includes a cavity having an antenna. The cavity includes a light source and a lens to direct a light generated by the light source through an opening. The opening has a dimension that is proportional to an operating frequency of the antenna.

First claim

What is claimed is:

1 . An electronic device, comprising:
a cavity having an antenna, the cavity including:
a light source; and
a lens to direct a light generated by the light source through an opening, the opening having a dimension that is a multiple of an operating frequency of the antenna.

2 . The electronic device of claim 1 , wherein the cavity includes a barcode scanner.

3 . The electronic device of claim 1 , comprising a second cavity having a second antenna, the second cavity including:
a second light source; and a second lens to direct a second light generated by the second light source through a second opening, the second opening having a second dimension that is proportional to a second operating frequency of the second antenna.

4 . The electronic device of claim 3 , comprising a third cavity having a third antenna, the third cavity including:
a third light source; and a third lens to direct a third light generated by the third light source through a third opening, the third opening having a third dimension that is proportional to a third operating frequency of the third antenna.

5 . The electronic device of claim 4 , wherein the opening is for a laser aiming device, wherein the second opening is for an image sensor, and the third opening is for a light emitting diode (LED).

6 . An electronic device, comprising:
a cavity having an opening, the cavity including:
a light source; and
a lens having an antenna on a surface of the lens, the lens to direct a light generated by the light source through the opening.

7 . The electronic device of claim 6 , wherein the cavity includes a laser aiming device, an image sensor, a light emitting diode (LED), or a combination thereof.

8 . The electronic device of claim 6 , wherein a length of the antenna is a multiple of a wavelength of an operating frequency of the antenna.

9 . The electronic device of claim 6 , wherein a dimension of the opening is proportional to a wavelength of an operating frequency of the antenna.

10 . The electronic device of claim 6 , wherein the surface of the lens has a first portion and a second portion, the first portion to direct the light generated by the light source and the second portion contiguous to the first portion, and wherein a metal trace of the antenna is mounted to the second portion.

11 . An electronic device, comprising:
a cavity having an opening, the cavity including:
a light source;
a printed circuit board (PCB) having an antenna, the PCB located behind the light source; and
a lens to converge electromagnetic (EM) waves of the antenna at a focal point, the focal point located in proximity to the opening.

12 . The electronic device of claim 11 , wherein a first side of the PCB is a decoder of an image sensor and a second side of the PCB is the antenna, the second side opposite the first side.

13 . The electronic device of claim 11 , wherein an interior surface of the cavity is coated in a transparent conductive oxide.

14 . The electronic device of claim 11 , wherein the lens is a convex lens.

15 . The electronic device of claim 11 , wherein the cavity includes a guide structure located outside a path of a light generated by the light source, the guide structure to direct the EM waves of the antenna through the opening.
