Up to now there has been an intense research on metamaterials based on Composite Right/Left Handed (CRLH) approach and several applications based on this approach have been developed. Most of the published CRLH cells are composed of an interdigital-capacitor and a stub-inductor implemented on microstrip technology. In previous work, the design and simulation results of a modified CRLH unit cell endowed...
The next generation of wireless communication is a ubiquitous radio system concept, providing wireless access from short-range to wide-area, with one single reconfigurable and adaptive system for all envisaged radio environments. This paper presents the design approach of RCO (reconfigurable concurrent oscillator) that simultaneously generates two or more signals of different frequencies that eliminate...
This paper describes the high-frequency characteristics of a multilayered planar transformer consisting of two planar coils and Co-Fe amorphous magnetic films. The parameters of transformer operation obtained by finite element method (FEM) calculations are compared with measured values. The analysis shows that characteristic evaluation is useful for a simple understanding of the operation of a transformer...
