In the current study, a frequency-tunable mechanical tuning coupler based on coupled line structure is proposed, which shall have high stability and flexibility of tuning. This microstrip technology. composed by baseplate for signal transmission mobile plate By mechanically rotation angle, coupling length changed tunability achieved. The operating frequency can be tuned from 1.02GHz to 1.27GHz ...

An SPICE compatible model for multiple coupled nonuniform lossless transmission lines (TL's) is presented. The method of the modeling is based on the steplines approximation of the nonuniform TLs and quasi-TEM assumptions. Using steplines approximation the system of coupled nonuniform TLs is subdivided into arbitrary large number of coupled uniform lines (steplines) with different characteristi...

Impedance matched and low loss transmission lines are essential for optimal energy delivery through an integrated optical or plasmonic nanocircuit. A novel method for the measurement of the attenuation and propagation constants of an antenna-coupled coplanar strip (CPS) transmission line is demonstrated at 28.3 THz using scattering-type scanning near-field optical microscopy. Reflection of the ...

An electromagnetically coupled feed arrangement is proposed for simultaneously exciting multiple concentric ring antennas for multi-frequency operation. This has a multi-layer dielectric configuration in which a transmission line is embedded below the layer containing radiating rings. Energy coupled to these rings from the line beneath is optimised by suitably adjusting the location and dimensi...

Advanced numerical linear circuit models for parallel microstrip coupled line sections have been developed by Applied Wave Research (AWR) for use with their Microwave Office simulation program. The linear elements incorporate closedform solution techniques that may be evaluated with a linear circuit simulator. The response of the elements provides a high degree of accuracy with respect to elect...

The design of modified Wilkinson power divider is done by dividing Quarter wavelength transmission line into two, in-between that complex isolation component and compensation capacitor is added. Complex isolation component provides physical separation and electrical isolation between two output ports. It consist of parallel or series RLC circuit is chosen to realize. To get the widest bandwidth...
