In this paper, the design of compact, wideband and tunable antenna is presented. The proposed antenna is consisting of a U-slot, stacked, shorted rectangular patch and complementary split ring resonator on ground plane. The antenna utilizes the shortedwall, stacked structure and complementary split ring resonator for size reduction and wideband characteristics. The antenna tuning is realized by using PIN diode. By making PIN diode ON and OFF, antenna may be configured to wideband or dual band mode. Both the simulated and experimental results are presented. The proposed antenna provides a good radiation pattern and a relatively constant gain over entire band of frequency. The proposed antenna achieves a 15.38% size reduction with wideband characteristics.

Following recent findings on metamaterials, a miniaturized microstrip patch antenna loaded with a complementary split ring resonator (CSRR) was investigated for multiband operation. The proposed structure has a CSRR loaded in the base of the antenna to improve its performance and to make it a metamaterial. Metamaterials exhibit qualitatively new electromagnetic response functions that cannot be found in nature. The CSRR-loaded base allows simultaneous operation over several frequencies. Here, a total of seven bands were achieved by loading the patch antenna with the CSRR. The seven bands were centered around frequencies of 4.33 GHz, 5.29 GHz, 6.256 GHz, 7.066 GHz, 7.846 GHz, 8.86 GHz, and 9.75 GHz. Design results were obtained by using a high-frequency structure simulator that is used for simulating microwave passive components.

It is known that complementtary split ring resonators (CSRR) can be used for reducing the size of microwave circuits. In this paper, the length of the 90 degrees branch line in L-Band power divider is reduced by implementing the CSRR in the ground plane underneath the branch line. The overall reduction in foot print of the proposed approach is 37% when compared to the conventional power divider. The power divider operates from 1.65 GHz to 1.8GHz, with nearly equal power division of 3.4dB. The measured isolation between the output ports is 22.73dB.

Dual split ring resonator based Metamaterial sensor materials is presented in this paper. This complementary split ring resonator (CSRR) is etched in the ground plane on back of the Microstrip line. Full wave electromagnetic simulation is done to verity the resonance phenomenon. Presented metamaterial sensor shows good result around 6GHZ. Simulation results show S21 with -31 dB notch depth at resonant frequency. Electromagnetic properties like effective electric permittivity (epsilon) and magnetic permeability (mu) of the sensor are derived from S-parameters simulation. Standard photolithography technique is used in fabrication of this metamaterial sensor using low cost FR4 substrate. S-parameters are measured by using Keysight technologies Vector Network Analyzer N5224B. S-parameters simulated and measured results show good agreement. By measurement of only resonant frequency (CHz) and the magnitude (dB) response of the sensor with material under test (MUT) the dielectric constant of the material can be calculated numerically. This nondestructive measurement technique has many applications in material testing for security and bio-sensing.

In this paper, a compact coplanar waveguide (CPW) based dual-band bandpass filter has been proposed. The modified complementary split ring resonator (CSRR) structure at CPW ground plane is investigated for designing of dual-band bandpass filter with minimum insertion loss. The zeroth order resonance (ZOR) frequency depends on shunt parameter due to open ended boundary condition. The dual-band bandpass filter with return loss 21 and 20 dB, insertion loss 0.5 and 0.4 dB at 1.8 and 3.2 GHz, respectively, are simulated and measured. The measured 3 dB fractional bandwidths are 92.7% and 18.8% with respect to their centre frequencies of passbands. The simulated and measured results are showing good agreement in the passband. The electrical size of designed filter is 0.10 lambda(0 )x 0.09 lambda(0) x 0.007 lambda(0), where lambda(0) is the free space wavelength at the resonance frequency of first pass band. It is suitable for a global system for mobile (GSM) and long term evolution (LTE) in different service bands of 900, 1800, 1900 and 2300 MHz wireless communication applications.

The integration of nanomaterials with the microwave technology is a significant step toward the development of low-cost and low-power RF gas sensors. But, the issues associated with materials like insignificant surface area and poor conductivity, are harriers for the rapid detection of wide range of gas concentrations. In this paper, we demonstrate the proof-of concept using an RF complementary split ring resonator (CSRR) integrated ZnO/N-doped graphene (NGN) nano-hybrid to study the gas sensing properties. This RF device senses the presence of ammonia based on the change in the electrical conductivity of the nanohybrid material upon gas exposure. For this, we have designed and fabricated various new CSRR structures, namely, the meander (M-CSRR) and the CSRR, with the concentric-etched square pattern (SP-CSRR) other than the conventional CSRR (C-CSRR). The fabricated CSRRs are coated with the solvothermal methodically prepared ZnO/NGN nanomaterials and a comparison among them is also made. The comparison revealed that the SP-CSRR coated ZnO/NGN sensor had the maximum shift in the S21 resonance frequency (Delta f(S21) = 13 MHz at 100 ppm) among all at room temperature. Furthermore, the SP-CSRR-ZnO/NGN sensor exhibited a large-S21 frequency shift of 133 MHz for 500 ppm of ammonia and has shown excellent reproducibility with 0.05% of variation. We have also projected the plausible sensing mechanism for this RF sensing device.

In this paper a compact patch antenna backed with artificial meta-surface known as reactive impedance surface (RIS) is designed for circular polarization in the ISM band. The antenna consists of an asymmetric diagonal slits with pair of complementary split ring resonators (CSRRs) on patch over the RIS structure. Asymmetric slits and pair of CSRRs are inserted on radiating patch to achieve circular polarization. RIS is used for improving the radiation characteristics of the antenna, while RIS-based patch provides good impedance matching over a broad frequency range. Simulated results are in good agreement with the measured results.

In this article, microstrip patch antenna with complementary split ring resonator (CSRR) loaded ground plane is proposed for gain improvement. Gain was improved by introducing CSRR slots on the ground plane. The proposed antenna is designed, fabricated, and tested. Measured results are in good agreement with simulation results. The proposed antenna has a size of 40 x 46 x 1.6 mm(3). The measured impedance bandwidth is 100 MHz (return loss <-10 dB) from 2.4 to 2.5 GHz, which covers instruments, scientific and measurement (ISM) band applications. Omnidirectional radiation pattern obtained in H-plane and bidirectional radiation pattern obtained in E-plane. Parametric study of CSRR was done to obtain best results. The proposed antenna is simple, has good radiation pattern, and very good gain of 5.93 dBi at resonant frequency. Size reduction of 10% was also achieved and bandwidth is slightly greater than unloaded antenna. (c) 2015 Wiley Periodicals, Inc. Microwave Opt Technol Lett 57:292-296, 2015

IEEE TRANSACTIONS ON ANTENNAS AND PROPAGATION 2009年第10期57卷 3352-3355页

作者： Zhang, Hui Li, You-Quan Chen, Xi Fu, Yun-Qi Yuan, Nai-Chang Natl Univ Def Technol Coll Elect Sci & Engn Changsha 410073 Hunan Peoples R China

A novel kind of circular polarization and dual-frequency linear polarization microstrip antennas is proposed. The designs are based on the anisotropic property of the complementary split ring resonator. When the complementary split ring resonator is etched on the patch of the probe-fed microstrip antenna, the gap orientation asymmetric or symmetric to the current propagating direction will render the antenna to radiate circular polarization waves or dual-frequency linear polarization waves. Details of the experimental results compared with the simulated results are presented and discussed.
