Abstract

A wireless communication device is configured to provide wireless communication to a host device when disposed in a mated position with the host device. The wireless communication device includes a transceiver, a controller in communication with the transceiver, and a modem in communication with the controller. The wireless communication device further includes a printed circuit board (PCB) having a first inductor loop, and an antenna having second inductor loop inductively coupled with the first inductor loop.

Claims

1. A wireless communication device configured to provide wireless communication to a host device when disposed in a mated position with the host device, the wireless communication device comprising:

a modem in communication with the controller;

a printed circuit board (PCB) having a first inductor loop; and

an antenna having second inductor loop inductively coupled with the first inductor loop.

2. The wireless communication device of claim 1, wherein the first and second inductor loops each have width W and are separated by a distance S, wherein W is greater S.

3. The wireless communication device of claim 1, wherein the first inductor loop has an output gap and the antenna has a feed gap disposed in an opposite location from the output gap.

4. The wireless communication device of claim 1, wherein the second loop is disposed above the first loop and the antenna is disposed above the second loop.

5. The wireless communication device of claim 1, wherein the antenna is disposed substantially normally to the PCB.

6. The wireless communication device of claim 1, wherein the second loop is disposed above the first loop and the antenna is disposed in a plane parallel to that of the first and second loops but not above the first or second loops.
