A half-width microstrip leaky-wave antenna on a circular substrate is proposed and investigated. A microstrip on a circular substrate has a broader bandwidth for free-space leaky-wave radiation than a planar microstrip. A half-width microstrip has si
Low-loss dielectric ceramics in portable and wireless devices has gained significant amount of interest over the years. This review article describes different types of low-loss dielectric ceramic materials used for dielectric resonator, ceramic subs

An effective simultaneous evaluation method for the complex permittivity and permeability of lossy materials is proposed by applying it to an arbitrarily shaped cross-sectional post placed in a rectangular waveguide. We use one sample and only measur

The broadband feeder line is investigated to exploit the broadband nature of leaky-wave antenna. The feeding structure is realized by inserting the composite right/left-handed transmission line (CRLH-TL) into the feeder. Microstrip CRLH-TL feeder lin

The extended version of spectral domain approach (ESDA) is applied to evaluate the scattering characteristics of discontinuities in coaxial line. Discontinuities may be in inner and/or outer conductor of coaxial line. This method secures the high acc

A novel bi-directionally fed phased-array antenna (BiPA) is presented. A BiPA can operate at half the phase shift of the conventional antenna with the same performance, leading to smaller size and lower cost. Main components of a BiPA are antenna ele

A full-wave analysis by the extended spectral-domain approach is successfully applied to solve the cylindrical coplanar-waveguide problem. The analysis incorporates the effects of the edge singularities properly and can afford the efficient and accur
