Microwave properties of Ba0.5Sr0.5TiO3 thin film coplanar phase shifters

Coplanar waveguide transmission lines have been used to show that the temperature dependent properties of Ba 0.5 Sr 0.5 TiO 3 thin films used for microwave phase shifters in the frequency range 45 MHz– 50 GHz are correlated strongly with the microstructure of the films. The highest tunability and figure of merit of the phase shifters were obtained for films with the narrowest ferroelectric-para...

Mechanically Steerable Array Antennas Using Controllable Microwave Phase Shifters

Low-cost antenna systems are important issues of the recent and the future flexible wireless communication systems. The most flexible satellite to ground/airplane communication systems are based on the phased-array antenna technology. However, the cost of phased array antenna is related to the number of active elements, and the present systems are too expensive for many commercial/military appl...

Microwave-assisted solid-phase synthesis of peptoids.

Microwave irradiation reduces the reaction time for the solid-phase synthesis of peptoids. Under these conditions, coupling of each residue requires only 1 min. The purity and yields of peptoids synthesized in this way are as good as or better than those achieved using standard methods. [reaction: see text]
