The Effect of Differential Driver Asymmetries on Common-Mode Frequency Spectrum
(Společnost pro radioelektronické inženýrství, 2003-04)
A frequency spectra determination of the common-mode signal due to the differential driver asymmetries is presented. The analytical expression for the Fourier series is developed and the evaluations for different dependencies ...
A Novel Bandpass Filter Using a Combination of Open-Loop Defected Ground Structure and Half-Wavelength Microstrip Resonators
(Společnost pro radioelektronické inženýrství, 2010-09)
This paper deals with a defected ground structure (DGS) open-loop resonator analysis and bandpass filter design, using coupled DGS and microstrip resonators. The combination of DGS and microstrip resonators allows using ...
Compact Elliptically Tapered Slot Antenna with Non-uniform Corrugations for Ultra-wideband Applications
(Společnost pro radioelektronické inženýrství, 2013-04)
A small size elliptically tapered slot antenna (ETSA) fed by coplanar waveguide (CPW) for ultra-wideband (UWB) applications is proposed. It is printed on an FR4 substrate and occupies a size of 37×34×0.8 mm³. A pair of ...
