RESONANT FREQUENCY PRESSURE SENSOR
First Claim
Patent Images
1. A pressure sensor comprising:
- an antenna member adapted to be resonantly responsive to a desired frequency of electromagnetic radiation;
a compressible dielectric material having an effective dielectric constant positioned in proximity to the antenna member and operably connected with the antenna member for effecting a resonant frequency shift in the antenna member responsive to changes in the effective dielectric constant of the compressible dielectric material; and
,a housing member for housing the antenna member in a desired proximity to the compressible dielectric material.

Abstract
A pressure sensor (S) includes an antenna member (10) that is adapted to be resonantly responsive to a desired frequency of electromagnetic radiation (12). An inductance changing body formed from a compressible dielectric material (14) is positioned in proximity to the antenna member (10). A housing member (16) houses the antenna member (10) in a desired proximity to the compressible dielectric material (14). The compression of the dielectric material (14) changes the effective dielectric constant of the antenna (10).
