Layered structure made of high-/spl epsiv/ dielectric and piezo-controlled air slot, filling various type waveguides, is used as tunable low loss wide-band phase shifter. A contemporary piezoelectric… (More)
New principle of microstrip resonators and filters tuning is developed and studied. Realized idea is the operation by the effective dielectric constant (/spl epsiv//sub eff/) of substrate using… (More)
A novel approach, utilizing piezoelectric actuators to control filters, resonators, and phase shifters with the minimum insertion loss, is described. Tunable, low-loss microwave devices can be… (More)
Low loss dielectric phase shifter is elaborated on the base of "dielectric-air slot" layered structure. Its effective dielectric constant (/spl epsiv//sub ef/) is controlled by means of fast… (More)
A novel concept for controlling of tunable microstrip resonators is proposed. The microstrip stub control is realized by detaching a part of the stub from the substrate. The air gap between the… (More)
Tunable by the mechanical reconfiguration low loss dielectric filter and wide-band phase shifter are elaborated. Dielectric or metallic parts of device should have a piezo-dirigible air gap between… (More)
Report presents design, simulation and study of new kind of microwave device, namely piezo-driven dielectric phase shifter. The study develops principles of hybrid type piezo-controlled devices.
Thin dielectric resonator consisting only of a low-loss dielectric substrate and a deposited film is proposed for the electrode-free microwave characterization of thin films and substrates. In-plane… (More)
The tunable filters based on uncoupled dielectric resonators are presented. The main idea is to provide a minimal coupling between dielectric resonators.
