“…The structure of the SRR/CSRR can be understood and analyzed by modeling the equivalent LC (inductance and capacitance) and applying the resonance phenomenon. There is a growing trend to realize communication and sensing applications using SRRs and CSRRs owing to their high quality (Q) factor [18,19,20,21,22,23,24,25,26,27,28,29,30]. The CSRR consists of a single ring, etched on the top metallization or in the ground plane with a particular orientation.…”

In this paper, a complementary split-ring resonator (CSRR)-loaded patch is proposed as a microfluidic ethanol chemical sensor. The primary objective of this chemical sensor is to detect ethanol’s concentration. First, two tightly coupled concentric CSRRs loaded on a patch are realized on a Rogers RT/Duroid 5870 substrate, and then a microfluidic channel engraved on polydimethylsiloxane (PDMS) is integrated for ethanol chemical sensor applications. The resonant frequency of the structure before loading the microfluidic channel is 4.72 GHz. After loading the microfluidic channel, the 550 MHz shift in the resonant frequency is ascribed to the dielectric perturbation phenomenon when the ethanol concentration is varied from 0% to 100%. In order to assess the sensitivity range of our proposed sensor, various concentrations of ethanol are tested and analyzed. Our proposed sensor exhibits repeatability and successfully detects 10% ethanol as verified by the measurement set-up. It has created headway to a miniaturized, non-contact, low-cost, reliable, reusable, and easily fabricated design using extremely small liquid volumes.

“…The oscillator with compact size has been designed based on CSRR-loaded SIW resonator [7]. However, most of those works are focus on the design of single frequency oscillator [1]- [4], [7]. Manuscript Recently, several design methods have been reported to realize dual-band oscillators, which are able to cover two different channels.…”

A novel C-band concurrent dual-band oscillator is presented in this paper. Two diplexers are cascaded back-to-back to realize two loop sub-oscillators. The phase noise of the oscillator is reduced significantly by using the cascaded high-Q diplexers as the frequency stabilization elements. Meanwhile, a highly pure dual-band signal was observed at the output port, which is contributed to the isolation characteristic of the diplexers. The diplexers can suppress the interaction between the two sub-oscillators. To obtain the property of compact size and high-Q factor, the SIW-CSRR structure is introduced into the design of diplexers. A C-band prototype has been designed and fabricated. The measured phase noise of the dual-band oscillator is dBc/Hz and dBc/Hz at 100 kHz offset from 4.18 and 5.49 GHz oscillation frequencies, which correspond to the figure-of-merit (FOM) of 188.7 and 189.1 dBc/Hz, respectively. The second-order and third-order intermodulation products of the two oscillation signals are suppressed to below dBc, as compared to the 4.18 GHz signal.Index Terms-Complementary split-ring resonator (CSRR), diplexer, dual-band, oscillator, SIW.

“…However, Q factor is very important to oscillator performance. Oscillators achieved by SIW applications have been reported in recent years [4][5] [6]. In this paper, SIW is used as a resonator to achieve an x-band low phase noise oscillator.…”

In this paper, a novel x-band oscillator using a substrate integrated waveguide (SIW) resonator has been proposed and developed for microwave applications. A high integrated X-band oscillator, which consists of a SIW resonator whose dimension is 15mm in length and 9.2mm in width, is designed. An NEC low noise GaAs JFET NE3515s02 is used as the active device. The oscillator is designed by negative resistance method based on Agilent ADS. The oscillator frequency is mainly decided by the SIW resonator. Measured results show that the oscillation frequency is 9.89GHz. The output power is 5.75 dBm and phase-noise of -117 dBc/Hz @1MHz, which is very suitable for applications of radar and communication systems.
