“…However, this wireless transmission mode using external antennas requires excessive volume. Antenna integrated sensor [27][28][29][30][31] is a novel technology with potentials for wireless monitoring of parameters in harsh environments. It miniaturizes the sensor system J o u r n a l P r e -p r o o f by embedding the sensitive element inside the substrate of antenna, and perceives the ambient environment through the resonant frequency change of the antenna.…”

“…A high-quality factor, SIW resonator, having confined energies at the centre, is utilized as a humidity-sensing sensor [8]. A gas detection sensor is designed using a multi-mode (Specifically TE101 and TE102) SIW resonator [12]. A complementary split ring resonator-based sensor for liquid dielectric characterization is reported in [13], in which the material under testing is placed in a normal orientation to the sensor surface.…”

A compact, cylindrical dielectric resonator antenna (CDRA), using radio frequency signals to identify different liquids is proposed in this paper. The proposed CDRA sensor is excited by a rectangular slot through a 3-mm-wide microstrip line. The rectangular slot has been used to excite the CDRA for H E M 11 mode at 5.25 GHz. Circuit model values (capacitance, inductance, resistance and transformer ratios) of the proposed CDRA are derived to show the true behaviour of the system. The proposed CDRA acts as a sensor due to the fact that different liquids have different dielectric permittivities and, hence, will be having different resonance frequencies. Two different types of CDRA sensors are designed and experimentally validated with four different liquids (Isopropyl, ethanol, methanol and water).

“…Another remarkable feature was enhanced sensitivity without using any coating material, unlike existing humidity sensors. In [ 31 ], an SIW resonator (with TE 101 and TE 102 modes) functionalized with tin oxide (SnO 2 ) powder was proposed to detect hydrogen gas. The influence of the size and topology of the functionalized area, substrate permittivity, and grain size of the micro powder (tin oxide) on the sensitivity of the device was investigated.…”

Microwave resonators working as sensors can detect only a single analyte at a time. To address this issue, a TE20-mode substrate-integrated waveguide (SIW) resonator is exploited, owing to its two distinct regions of high-intensity electric fields, which can be manipulated by loading two chemicals. Two microfluidic channels with unequal fluid-carrying capacities, engraved in a polydimethylsiloxane (PDMS) sheet, can perturb the symmetric electric fields even if loaded with the two extreme cases of dielectric [ethanol (E), deionized water (DI)] and [deionized water, ethanol]. The four layers of the sandwiched structure considered in this study consisted of a top conductive pattern and a bottom ground, both realized on a Rogers RT/Duroid 5880. PDMS-based channels attached with an adhesive serve as the middle layers. The TE20-mode SIW with empty channels resonates at 8.26 GHz and exhibits a −25 dB return loss with an unloaded quality factor of Q ≈ 28. We simultaneously load E and DI and demonstrate the detection of the four possible combinations: [E, DI], [DI, E], [E, E], and [DI, DI]. The performance of our proposed method showed increases in sensitivity (MHz/εr) of 7.5%, 216%, and 1170% compared with three previously existing multichannel microwave chemical sensors.
