Patent ID: 8358970

Claim:
A modular device for repeating RF communication signals, the device comprising: a planar housing that has height and width dimensions that are a multiple of the thickness dimension, the planar housing defining a plane and having generally oppositely facing surfaces; at least one antenna positioned on each of said generally oppositely facing surfaces for radiating energy from each of the surfaces; at least one of the antennas on a surface configured to act as a transmit antenna for transmitting RF communication signals and at least one antenna on an oppositely facing surface configured to act as a receive antenna for receiving RF communication signals; electronic circuitry positioned in the planar housing and operatively coupling the receive antenna to circuitry for handling the received RF communication signals and operatively coupling the transmit antenna to circuitry for providing RF communication signals to transmit; the planar housing including at least one planar layer positioned parallel to the plane of the housing between the oppositely facing surfaces and antennas positioned thereon, the planar layer configured to block RF communication signals of one antenna from being received by the other antenna for providing side-to-side isolation between the antennas.
