System for remotely controlling an electrical switching device
First Claim
1. A system for remotely controlling an electrical switching device, comprising:
- a mounting fixture configured to be mounted in a wall and having the electrical switching device supported by the mounting fixture;
a cover configured to cover at least a portion of the mounting fixture mounted in the wall;
a shielding plate configured to have high electrical conductivity, the shielding plate being mounted proximate to the mounting fixture between the cover and the electrical switching device; and
a directional, non-isotropic radio frequency (RF) antenna sized to fit within the cover and configured to transmit RF signals, the RF antenna being located between the shielding plate and the cover at a predetermined distance from the shielding plate, wherein the predetermined distance is selected to increase a capability of the RF antenna to send and receive the RF signals.

Abstract
A system for remotely controlling an electrical switching device is disclosed. The system includes a mounting fixture configured to be mounted in a wall. An electrical switching device is supported by the mounting fixture. The system also includes a cover configured to cover at least a portion of the mounting fixture. The system further includes a shielding plate configured to have a high electrical conductivity. The shielding plate is mounted proximate to the mounting fixture between the cover and the electrical switching device. The system also includes a directional, non-isotropic radio frequency (RF) antenna sized to fit within the cover and configured to transmit RF frequency signals. The RF antenna is located between the shielding plate and the cover at a predetermined distance from the shielding plate. The predetermined distance is selected to increase the capability of the RF antenna to send and receive the RF signals.
