Abstract:
1. A method of reducing coupling of radio frequency (RF) interrogated surface acoustic wave (SAW) based sensors to external bodies, comprising the steps of: providing a surface acoustic wave sensor element, said surface acoustic wave sensor element having first and second electrical terminals; providing an electrically conductive housing; providing a feed through electrical connection pin having first and second end portions, the second end portion passing through a portion of the electrically conductive housing; providing electrical isolation between the feed through electrical connection pin and the electrically conductive housing; connecting the second end portion of the feed through electrical connection pin to the first electrical terminal of the surface acoustic wave sensor element; connecting the second electrical terminal of the surface acoustic wave sensor element to the electrically conductive housing; providing an antenna element having first and second end portions; and connecting the first end portion of the antenna element to the first end portion of the feed through electrical connection pin.
