This paper presents a compact bandpass filter with stopband and high attenuation by using multilayer folded broadside-coupled quarter-wavelength stripline resonators in a low-temperature co-fired ceramic (LTCC) substrate. The proposed bandpass filter centered at 1.1 GHz with a fractional bandwith of 4.5 % shows the first spurious frequency at 3.8 times the center frequency. In comparison to the...

The effect of the patterning process on the nonlinearity of the microwave surface resistance RS of YBCO thin films is investigated. With the use of a sapphire dielectric resonator and a stripline resonator, the microwave RS of YBCO thin films was measured before and after the patterning process, as a function of temperature and the rf peak magnetic field in the film. The microwave loss was also...

1. Abstract In this design, the dual band dipole antenna feed network with wide bandwidth tapered microstrip balun is studied. The design and experimental results of low profile embedded microstrip dipole antenna with tapered microstrip balun shows fairly good performances. The feed network of the design with wider bandwidth and lower power loss tapered microstrip line to overlap coplanar strip...

Beam position monitor (BPM) characterization has been widely studied at the synchrotron. The characteristic impedance of a stripline BPM was designed using simulation and measured time-domain reflectometer method. mechanical electrical parameters feedthroughs with buttons used for BPMs were measured. Special care taken in analysis consistency four channels BPM. sorted based on their capacitance...

This paper has presented the characteristic impedance and signal propagation delay time for both surface and embedded microstrip lines that comprise a conducting strip line with width w, thickness t of conductivity σ, on a substrate of thickness h, relative permittivity εr, relative permeability sub, on top of an infinite grounded electrode. The strips couples to the ground plane. It is observ...

─ A novel broadband 3-dB directional coupler design method utilizing HFSS and realization are given in this paper. It is realized in stripline, showing great agreement with the simulation and design format. The unique property of this design method is that it unnecessitates both a feedback from the realization for broadbanding and an additional smoothing of transition between coupled sections o...

A design of back-to-back tapered line transition is presented. The transition is suitable for application in feeding arrays of double-side printed antennas. Tapered transmission lines are transmission line whose characteristic impedance is tapered from one value to another. Back-to-back circuits of identical transitions are designed, measured, and their characteristics are compared with theoret...

EM1 associated with inter-board connection was studied through common-mode current measurements and FDTD modeling for stacked-card and module-on-backplane configurations. Three types of connections were investigated experimentally including an open pin field connection, an “ideal” semi-rigid coaxial cable connection, and a production connector. Both microstrip and stripline signal routing on th...

We study theoretically and experimentally the response of a microwave superconducting stripline resonator, integrated with a microbridge, to a monochromatic injected signal. We find that there is a certain range of driving parameters in which a novel nonlinear phenomenon emerges, and self-sustained modulation of the reflected power off the resonator is generated by the resonator. A theoretical ...
