Abstract

Embodiments of an apparatus and system are described for a coaxial antenna. An apparatus may comprise, for example, an integrated circuit and a coaxial cable coupled to the integrated circuit and arranged to operate as an antenna, the coaxial cable comprising an inner conductor layer and at least one insulator layer, wherein one or more portions of the inner conductor layer are exposed to allow the exposed inner conductor layer to operate as a radiating element for the antenna. Other embodiments are described and claimed.

First claim

The invention claimed is:

1. An apparatus, comprising
an enclosure;
an integrated circuit enclosed within the enclosure; and
a coaxial cable enclosed within the enclosure and arranged to operate as an antenna, a first end of the coaxial cable coupled to the integrated circuit, a second end of the coaxial cable terminating in an open space within the enclosure, the coaxial cable comprising an inner conductor layer and at least one insulator layer, wherein the inner conductor layer comprises solid or stranded conductive metal wire, wherein two or more non-contiguous portions of the inner conductor layer are exposed to allow the exposed inner conductor layer to operate as a radiating element for the antenna, wherein a length of each of the two or more non-contiguous portions of exposed inner conductor layer and a length between each of the two or more non-contiguous portions of exposed inner conductor layer are selected to correspond to a desired resonant frequency for multiband operation of the antenna and to enable the apparatus to send and receive information using both a wireless local area network (WLAN) and a long term evolution (LTE) network.

2. The apparatus of claim 1 , the coaxial cable comprising:
the inner conductor layer;
a dielectric insulator layer arranged to surround the inner conductor layer;
an outer conductor layer arranged to surround the inner conductor layer and the dielectric insulator layer; and
an outer insulator layer arranged to surround the inner conductor layer, the dielectric insulator layer and the outer conductor layer.

3. The apparatus of claim 2 , wherein the dielectric insulator layer and the outer insulator layer are removed in the area of the exposed inner conductor layer allowing radiation from the inner conductor layer to escape.

4. The apparatus of claim 1 , wherein the integrated circuit comprises one or more radio modules having a first coaxial connector and the coaxial cable is coupled to the one or more radio modules using a second coaxial connector coupled to the first end of the coaxial cable, the second coaxial connector configured to mate with the first coaxial connector.

5. The apparatus of claim 1 , wherein a length of at least one of the two or more non-contiguous portions of exposed inner conductor layer comprises approximately 60 mm corresponding to a frequency of approximately 2400-2485 MHz or approximately 214 mm corresponding to a frequency of approximately 700 MHz.

6. A system, comprising:
a digital display
an integrated circuit; and
one or more coaxial cables arranged around an outer perimeter of the digital display, each coaxial cable secured within the digital display, each coaxial cable having two or more non-contiguous exposed portions of an inner conductor configured to act as a radiating antenna element, the respective inner conductor of each coaxial cable comprising solid or stranded conductive metal wire, each coaxial cable comprising a first end coupled to the integrated circuit and a second end terminating in an open space within the display, wherein for each of the one or more coaxial cables, a length of each of the two or more non-contiguous exposed portions of the inner conductor and a length between each of the two or more non-contiguous exposed portions of the inner conductor are selected to enable multiband operation of the antenna and to enable the system to send and receive information using both a wireless local area network (WLAN) and a long term evolution (LTE) network.

7. The system of claim 6 , each of the one or more coaxial cables comprising
the inner conductor;
an inner insulator arranged to surround the inner conductor;
an outer conductor arranged to surround the inner conductor and the inner insulator; and
an outer insulator arranged to surround the inner conductor, the inner insulator and the outer conductor.

8. The system of claim 7 , wherein one or more portions of the inner and outer insulators are removed to expose a portion of the inner conductor to allow the exposed inner conductor to operate as the radiating antenna element.

9. The system of claim 6 , comprising one or more hinges arranged to couple the digital display to a device body containing the integrated circuit, wherein the first end of each coaxial cable is coupled to the integrated circuit using coaxial connectors on the first end of that coaxial cable and the integrated circuit, and wherein each coaxial cable is arranged to pass through at least one of the one or more hinges into a cavity created by the perimeter edges of the digital display.

10. A coaxial cable antenna, comprising:
an inner conductor comprising solid or stranded conductive metal wire;
an inner insulator arranged to surround the inner conductor;
an outer conductor arranged to surround the inner conductor and the inner insulator;
an outer insulator arranged to surround the inner conductor, the inner insulator and the outer conductor; and
a coaxial connector on a first end of the coaxial cable antenna, the coaxial connector configured to mate with a second coaxial connector to form an electrical connection with an integrated circuit, the coaxial cable antenna and the integrated circuit to be secured within a same enclosure, a second end of the coaxial cable antenna to terminate in an open space within the enclosure;
wherein two or more portions of the inner and outer insulators are removed to expose two or more non-contiguous portions of the inner conductor to allow the exposed inner conductor to operate as a radiating antenna element, wherein a length of each of the two or more non-contiguous portions of exposed inner conductor and a length between each of the two or more non-contiguous portions of exposed inner conductor are selected to enable the coaxial cable antenna to operate as a multiband antenna for sending and receiving information using both a wireless local area network (WLAN) and a long term evolution (LTE) network.

11. The coaxial cable antenna of claim 10 , wherein the inner insulator comprises one or more of a plastic, foam, polyethylene or Teflon insulator material, the outer conductor comprises one or more layers of dielectric material and the outer insulator comprises one or more solid insulating materials.
