Abstract
An Electrically Small antenna with narrow bandwidth suitable for nearfield sensor application is presented. The operation principle is based on a Distributed Reactive Nearfield Parasitic Element (DRNPE). The DRNPE unit cell with high distributed inductive reactance is introduced near a highly capacitive open ended CPW transmission line, provides a high impedance matching. The resonant frequency is independent of the transmission line parameters and hence can be tuned with respect to the DRNPE parameters. The prototype used as a sensor for the measurement of dielectric constant variation is also discussed. The simulation is carried out using Ansoft HFSS and measurement using HP8510C Vector Network Analyzer.
