Micromachined transmission lines for microwave applications
… characterization, and modeling of micromachined strip lines. The challenge of structuring this three-dimensional transmission line is solved by using the photosensitive resin SU-8 as the micromachinable material and as the dielectric in the strip line. Additionally, electrodeposition is applied …

Electromagnetic and Experimental Modeling of Waveguide-Based Spatial Power Combining Systems
… results. In addition, a QO parallel-plate stripline-slot amplifier system was designed, tested and compared to a QO open HDSBW amplifier system with Vivaldi-type antennas. Experimental results verify that a QO parallel-plate stripline-slot amplifier proposed in this dissertation can be …

Enhancing Signal Coverage for UHF RFID Systems
… an almost uniform field distribution along the strip-line can be achieved by setting the phase difference of two sources to be 90° or 270°. Furthermore, by adding a new track of strip-line and setting a proper phase difference, a side-power leakage suppression of up to 20 dB can be achieved with …
