Lead zirconium titanate (PbZr 0.52 Ti 0.48 O 3 and PbZr 0.30 Ti 0.70 O 3 ) films were prepared on MgO (100) substrate by the sol-gel method. Film Thickness, microstructure and crystalline structure of the films were investigated by scanning electron microscope (SEM) and X-ray diffraction analysis, respectively. Terahertz time-domain spectroscopy has been used to investigate the dielectric properties of ferroelectric Pb(Zr, Ti)O 3 thin films in the frequency range of 0.2 to 2.0 THz.
band Wilkinson power divider on L-SIAD is designed and fabricated at two frequency bands of 0.9 GHz and 1.8 GHz. An area reduction of about 40% can be achieved, compared with normal microstrip line circuit. It is shown that such an L-SIAD will have potential miniaturization of many planar components and antenna applications.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
