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 ).
