In this paper, we propose a paper-based pattern switchable antenna system using inkjet-
printing technology for bi-direction sensor applications. The proposed antenna system is …

A novel miniature sensor operating at 150 MHz for real-time sensing of fluid concentrations
is presented. The core of the sensor is a planar double-sided spiral split-ring resonator (DSS …

Microwave resonant sensors are limited in their current form to a static resonant frequency,
which can lead to misidentification when two materials or mixtures with similar dielectric …

With the development of modern wireless communication systems, the demand for high-
performance, multifunctional, low-cost, and compact antennas has been increasing …

This article reports on the design of continuously tunable true-time-delay (TTD) phase shifter
using transmission lines with simultaneously reconfigurable impedance and phase constant …

This paper proposes a new unbalance composite right/left handed (CRLH) transmission line
that consists of a normally magnetized ferrite-loaded rectangular waveguide. The left …

The permittivity response from 0.5 to 40 GHz of ethyl acetate (C 4 H 8 O 2), ethylene glycol
(CH 2 OH) 2, castor oil (C 57 H 104 O 9), liquid paraffin, and other fluids commonly used for …

In this article, we propose a novel microfluidic microstrip electromagnetic band gap (EBG)
sensor realized using cost-effective 3D printing technology. Microstrip sensor allows …

This communication presents a compact reconfigurable phase shifter based on negative-
