“…Due to the strong localization of the EM fields in the vicinity of resonant metallic elements, metamaterials exhibit a strong change of their EM response when a sample material is present [3]. Therefore, metamaterials have important applications in sensors [4]. Refractive index (RI) is an important physical parameter reflecting the intrinsic properties of a material.…”

A metamaterial sensor is designed in this paper which can be used to detect the refractive index of an unknown dielectric loaded on the top surface of a metamaterial absorber. The resonant frequency of the absorber will be changed with various refractive indexes of the loaded dielectrics. Especially, the resonant frequency of the sensor is uniquely related to the refractive index of the unknown dielectric with the constant thickness, the linear relation of which is obtained by simulation fitting. A prototype of the absorber is manufactured and measured, which testify the design theory and simulation results. The S fre of the proposed sensor is 0.3537 GHz/RIU, and the FoM can reach 11.0531 RIU −1 .

“…Moreover, for broadband mm-wave applications, it is often difficult to satisfy all-metal waveguide design specifications as dimensional parameters become too small even for advanced fabrication techniques [2]. Therefore, the SIW is attractive for the extension of microwave and millimeter wave applications such as cavity filters [3], antennas [4], phase shifter [5], power dividers [6] and Diplexers [7].…”

Recently, Substrate Integrated Waveguide (SIW) techniques have been noticed for millimeter wave devices in microwave applications. In this paper, we are developing a wide band directional 3 dB coupler with a phase of 90̊ phase delay in the range of 30-40 GHz based on periodic vias and multi hole structure. For achieving this wide bandwidth multi-section coupler is designed based on the theoretical modeling and the simulation result is compared with HFSS and CST with two different numerical methods show good performance with low insertion and return loss, broad operational bandwidth and high isolation. A fractional bandwidth is about 28.5 %.

“…In [3], phase shifter, which consists of a SIW section with two inserted metallic posts, is designed. In [4] and [5], phase shifts can be controlled digitally by burying NIP diodes within the substrate at specific positions, or placing PIN diodes on the metal material structure as a load. However, the bandwidths are limited and unsatisfactory.…”

Abstract-In this paper, an improved broadband substrate integrated waveguide (SIW) phase shifter with embedded air strips is presented. Phase shifter can be generated based on the variable widths of SIW, variable lengths of microstrip line and a row of embedded air strips. The simulated and measured results both show that this kind of SIW phase shifter has excellent performance for a wider bandwidth. Measured results indicate that the proposed SIW phase shifters for the 45 • and 90 • versions have achieved the fractional bandwidths of 59.6% from 10.2 to 18.85 GHz with the accuracy of 2.5 • , and of 62.3% from 9.5 to 18.1 GHz with the accuracy of 5 • , respectively. The return losses are better than 15.8 dB and 14.5 dB for 45 • and 90 • modules, respectively. In addition, the insertion losses are both found to be better than 1.6 dB in the considered band.
