  abstract: In this dissertation, "photonic bandgap (PBG) structures" and "piezoelectric transducer (PET) controlled devices" which are not conventionally used in microwaves are developed to obtain better performance with planar transmission-lines. A new technique of the PBG structure is applied to design band stop filter, high Q resonator, and varactor tunable resonator, which are demonstrated with analyses for optimum performance, full-wave simulations, and experimental results. The PET controllability is applied to microwave circuits: phase shifter, tunable resonator, tunable filter, voltage controlled dielectric resonator oscillator (VCDRO), demonstrated with theoretical and parametric analyses, simulations, and measurement data. For a phased array antenna, a multi-line PET phase shifter dramatically reduces the number of phase shifters, and a bi-directionally controlled dual-PETs phase shifter increases beam scanning range. A whole phased array antenna system consists of a wideband power divider, PET phase shifter, multi-frequency diplexer, and microwave monolithic integrated circuits (MMICs) amplifiers, which system shows the low-cost, four-channels and full-duplex functions. This dissertation's PBG and PET ideas and applications should be useful for microwaves and millimeter-waves.
