摘要
A sensor probe with reduced coupling between the various antenna elements and suppression of radio frequency interference. In one embodiment the sensor probe comprises a first antenna and a second antenna. A first and a second decoupling loop is electrically connected to one of the first and second antennas with current flow in opposite directions in the first and second decoupling loops. A third decoupling loop is electrically connected to another one of the first and second antennas and physically disposed between the first and second decoupling loops. Coupling between the first and second antennas is responsive to a location of the third decoupling loop relative to the first and second decoupling loops.
