Abstract

A new type of microwave position sensor is introduced. It is a microstrip stub resonator with slotted ground plane under the stub. It produces frequency-modulated signal with frequency corresponding to covering of the slot in the ground plane. The sensing is performed by sliding the metal plate over the slot. The structure is simple, low fabrication cost and compact. It is without multilayers, coupling, via holes, air bridges, active or discrete components.
