The digital twin (DT), which effectively represents the actual real-world physical system or process, has reshaped classic manufacturing, construction, as well healthcare industry. As for realizing DT, both sensing and communication functionalities are demanded, fully builds connectivity between world world. We first conducted a survey on current situation of DT combined with sensing. Inspired from this development sensing, in paper, we attempt to study annd technologies layer reduce...
Abstract The paper presents a dual‐wideband bandpass filter using multilayer broadside‐coupled microstrip‐coplanar waveguide (CPW) structure. half‐wavelength stepped‐impedance resonators at the top and bottom layers are broadside coupled in vertical direction through CPW‐multimode resonator (CPW‐MMR) mid layer, which forms mixed MMR. ultra‐wideband obtained from tight coupling is split into two passbands by introducing extra transmission zeros, good impedance matching achieved adopting...
In this paper, two improved microstrip-slot transition structures are proposed. The top layer microstrip lines with fan-shaped open-circuit terminals, and the bottom is cross-finger slotline which perpendicular to lines, short-circuit terminals of circular or petal-shaped. These work in 1-13GHz frequency band. HFSS used simulate these structures, S-parameters VSWR compared among ring slot, petal shaped slot original slot. results show that structure has best performance. S11 less than -19.5...
A compact bandpass filter (BPF) is proposed using two coplanar waveguide (CPW)- stripline transition structures. The top layer of the CPW-stripline structure a CPW with petal shape at short-circuit end, and bottom open end. input signal electromagnetically coupled from to stripline. simulation HFSS software shows that passband range 3.93-6.83GHz, center frequency 5.38GHz, fractional bandwidth (FBW) 53.9%, S11 better than -12.5dB S21 0.7dB in passband. This contains second 4.8GHz-5.0GHz low...
