Abstract
Disclosed is an apparatus and methodology for providing reduced coupling of radio frequency (RF) interrogated surface acoustic wave (SAW) based sensors to external bodies. Coupling, and therefore electrical loading of the sensor element, is reduced by providing an electrically conductive housing surrounding the SAW sensor element and by electrically coupling one terminal of the SAW sensor element to the electrically conductive housing. Electrical connection to an additional terminal of the SAW sensor element is provided by way of an electrically isolated connection through the electrically conductive housing.
