Abstract

An mobile device may include circuitry for transmissive communication and to operate with a ground reference. An antenna element may be in communication with the circuitry for transmissive communication to transmit or receive transmissive communication. A housing may house the circuitry for transmissive communication and the antenna element and may include a conductive circumferential case element. A coupling device may be electrically coupled to provide the ground reference over an elongate segment of the conductive circumferential case element.

First claim

What is claimed is:

1. A mobile device, comprising:
a circuit board;
circuitry for transmissive communication, mounted on the circuit board;
an antenna element mounted on the circuit board, in communication with the circuitry to transmit or receive transmissive communication;
an electromagnetic shield that covers the circuitry for transmissive communication, but not the antenna element;
a housing that houses the circuit board with the circuitry for transmissive communication and the antenna element, and that includes a conductive housing element having an elongate segment; and
a coupling device, housed by the housing and external to the electromagnetic shield, electrically coupled to the electromagnetic shield and to a radiation path of the antenna element, as well as coupled to the elongate segment of the conductive housing element.

2. The mobile device of claim 1 , wherein the conductive housing element includes a circumferential case element connected to peripheral edges of a case top and a case bottom.

3. The mobile device of claim 2 , wherein the case top and the case bottom are nonconductive.

4. The mobile device of claim 2 , wherein the circumferential case element forms a closed loop around the peripheral edges of the case top and the case bottom.

5. The mobile device of claim 2 , wherein the elongate segment has a length that corresponds to a wavelength that is cooperative with transmissive communication by the mobile device.

6. The mobile device of claim 2 , wherein the elongate segment includes first and second segments with a length that corresponds to a wavelength that is cooperative with transmissive communication by the mobile device.

7. The mobile device of claim 1 , wherein the mobile device is a wearable device or a portable device.

8. The mobile device of claim 1 , wherein the mobile device is an Internet of Things (IoT) device.

9. An apparatus, comprising:
circuitry for transmissive communication mounted on a circuit board;
an antenna element mounted on the circuit board and in communication with the circuitry to transmit or receive transmissive communication;
an electromagnetic shield that covers the circuitry for transmissive communication, but not the antenna element;
a housing that houses the circuit board with the circuitry for transmissive communication and the antenna element, and that includes a conductive circumferential case element having an elongate segment; and
a coupling device, housed by the housing and external to the electromagnetic shield, electrically coupled to the electromagnetic shield and to a radiation path of the antenna element, as well as coupled to the elongate segment of a conductive housing element.

10. The apparatus of claim 9 , wherein the conductive circumferential case element forms a closed housing circumference.

11. The apparatus of claim 10 , wherein the conductive circumferential case element provides external housing.

12. The apparatus of claim 9 , wherein the conductive circumferential case element is polygonal.

13. The apparatus of claim 9 , wherein the elongate segment has a length that corresponds to a wavelength that is cooperative with transmissive communication by the mobile device.

14. The apparatus of claim 9 , wherein the elongate segment includes first and second segments with a length that corresponds to a wavelength that is cooperative with transmissive communication by the mobile device.

15. The apparatus of claim 9 , wherein the apparatus is a wearable device or a portable device.

16. A system, comprising:
a circuit board;
circuitry to provide transmissive mounted on the circuit board;
an antenna element mounted on the circuit board, in communication with the circuitry to transmit or receive transmissive communication;
an electromagnetic shield that covers the circuitry for transmissive communication, but not the antenna element;
a housing to house the circuit board with the circuitry for transmissive communication and the antenna element, the housing including a conductive case element having an elongate segment;
a transmissive booster, housed by the housing and external to the electromagnetic shield, electrically coupled to the electromagnetic shield and to a radiation path of the antenna element, as well as coupled to the elongate segment of the conductive case element to boost efficiency of the transmissive communication.

17. The system of claim 16 , wherein the conductive case element includes a circumferential configuration.

18. The system of claim 17 , wherein the conductive circumferential case element has a length that corresponds to a wavelength that is cooperative with transmissive communication by a mobile device.
