The modifications of microwave slot transmission lines formed on the (Ba,Sr)TiO3 ferroelectric films were investigated to realize high quality factor millimeter-wavelength devices tunable by low bias voltages. The narrow inner electrodes inserted to a slot line form the novel type of the transmission lines, which was called multislot line (MSL). The MSL short-circuited and tunable resonators were tested at frequency ∼30 GHz. The MSL phase shifter merit factor was evaluated higher than 100 degree/dB at bias voltage lower 100 V. The comparatively high quality factors of tunable MSL resonators and phase shifters evidence on real prospects of novel topology approach to the development of such microwave devices as tunable band-pass filters and electronically steerable antennas.
