MINIATURE STUB AND FILTER DESIGNS USING THE MICROSHIELD TRANSMISSION LINE Conference Paper

abstract

• This paper presents new CPW-type stub and filter configurations which are useful approaches for compact microwave circuit design. It is shown that conventional open- and short-end quarter wavelength stubs can be shortened by a factor of three by folding the center conductor. Also, narrowband open-end stubs are demonstrated which have thin-film overlay capacitors integrated across the stub sections. In this work the circuits have been implemented using the microshield transmission line, a geometry in which a 1.4 /spl mu/m-thick dielectric membrane supports coplanar conducting lines virtually in free-space. The new stub configurations, however, are also suitable for standard substrate-supported CPW.<>
