Estudos e projetos de filtro interdigital em microfita para aplicação prática ao transponder do satélite ITASAT
(Universidade Federal do Rio Grande do NorteBRUFRNPrograma de Pós-Graduação em Engenharia ElétricaAutomação e Sistemas; Engenharia de Computação; Telecomunicações, 2012-05-07)
This work shows a theoretical analysis together with numerical and experimental
results of transmission characteristics from the microstrip bandpass filters with different
geometries. These filters are built over isotropic ...
Representation of transmission lines in modal domain using analytical transformation matrices
(2011-05-31)
The phases of a transmission line are tightly coupled due to mutual impedances and admittances of the line. One way to accomplish the calculations of currents and voltages in multi-phase lines consists in representing them ...
Corona effect in frequency dependent transmission line models
(2008-12-01)
The inclusion of the corona effect in a frequency dependent transmission line model is proposed in this paper. The transmission line is represented through a cascade of π circuits and the frequency dependence of the ...
