A Stacked Dual-Frequency Microstrip Patch Antenna for Simultaneous Shear and Pressure Displacement Sensing

This paper presents a simultaneous shear and pressure displacement sensor based on the microstrip patch antenna technology. The antenna sensor consists of a dual-frequency patch antenna, a superstrate, and a rectangular director. The two fundamental resonant frequencies of the patch antenna are influenced by the lateral and vertical positions of the director with respect to its radiation patch. Th...
