Abstract
A remote control electrical device which can communicate with a remote control device. The electrical control device is adapted to fit into a housing which fits into a wall mounting. The remote control electrical device can comprise a control circuit disposed in the housing, a transmitter disposed in the housing, a receiver disposed in the housing wherein said transmitter and said receiver are in communication with the control circuit. There is also a support plate having an inside face facing into the housing and an outside face facing away from the housing body. The support plate is coupled to the housing, wherein there is also an antenna disposed on the outside face of the support plate. This antenna does not receive any power-line AC frequencies or DC, instead it is capacitively coupled to the rest of the electrical components and disposed on the outside face of the support plate.
