This letter presents a second-order tri-band bandpass filter (BPF) designed using tri-section
stepped-impedance resonators (TSSIRs). The impedance ratios of the TSSIRs were …

A highly sensitive, passive relative humidity (RH) sensor using polyvinyl-alcohol (PVA)
dielectric film is presented. For the first time, PVA is investigated in microwave RF sensing …

In this article, a dual-functional microwave system with a single input port that can
simultaneously be used for antenna and sensor applications is presented. The dual …

In this article, a dual functional antenna system for communication and sensing applications
is designed on a single substrate having a common input port. The main motivation behind …

A self-coupled resonator consisting of asymmetrical parallel-coupled microstrip transmission
lines is proposed to design wide stopband dual-band bandpass filters. Due to the even-to …

In this paper, a low cost, printable chipless RFID humidity sensor is presented. The RFID
sensor is based on planar stepped impedance resonator (SIR) structure. Humidity sensing …

This paper presented a novel sensor based on a stepped impedance resonator, which can
measure the permittivities of materials at different resonant frequencies simultaneously. The …

This letter presents the design and implementation of a 24-/60-GHz millimeter-wave dual-
band on-chip bandpass filter using a 0.18-mum standard CMOS process. The concept of …

A selective miniaturized bandpass filter with wide stopband for TETRA band applications is
presented in this paper. Basic resonator used in the filter construction is an open stub …

Bandstop filters (BSFs) with high skirt selectivity as well as wide rejection bandwidth are
designed by means of open-ended λg/4 stepped-impedance resonators (SIRs) and spur …
