Signal to Noise Ratio Maximization in Quiet Zone Acquisitions for Range Assessment at Sub-millimeter Wavelengths
(Společnost pro radioelektronické inženýrství, 2012-06)This paper proposes a quiet zone probing approach which deals with low dynamic range quiet zone acquisitions. Lack of dynamic range is a feature of millimeter and sub-millimeter wavelength technologies. It is consequence ... -
Influence of Intermetallic Compounds on RF Resistance of Joints Soldered with Lead Free Alloys
(Společnost pro radioelektronické inženýrství, 2012-06)During soldering process intermetallic compounds as a reaction between solder and substrate are created. Physical properties of those compounds are different to properties of solder and substrate. The influence of intermetallic ... -
A Multiband CPW-Fed Slot Antenna with Fractal Stub and Parasitic Line
(Společnost pro radioelektronické inženýrství, 2012-06)This paper presents a multiband CPW-fed slot antenna with fractal stub and parasitic line. The conventional wideband slot antenna with fractal stub is modified by inserting the parasitic line surrounding the fractal stub ... -

Miniaturized Wideband Bandpass Filter with Wide Stopband using Metamaterial-based Resonator and Defected Ground Structure
(Společnost pro radioelektronické inženýrství, 2012-06)This paper presents a miniaturized wideband bandpass filter with wide stopband performance. It is shown that the coupled metamaterial-based resonators (MBRs) incorporating with the defected ground structure (DGS) can ... -
Downlink Video Streaming for Users Non-Equidistant from Base Station
(Společnost pro radioelektronické inženýrství, 2012-06)We consider multiuser video transmission for users that are non-equidistantly positioned from base station. We propose a greedy algorithm for video streaming in a wireless system with capacity achieving channel coding, ... -
Dual-Mode Dual-Band Microstrip Bandpass Filter Based on Fourth Iteration T-Square Fractal and Shorting Pin
(Společnost pro radioelektronické inženýrství, 2012-06)A new class of dual mode microstrip fractal resonator is proposed and developed for miniaturization of the dual band bandpass filter. The perimeter of the proposed resonator is increased by employing fourth iteration ... -
Wideband Characteristic Basis Functions in Radiation Problems
(Společnost pro radioelektronické inženýrství, 2012-06)In this paper, the use of characteristic basis function (CBF) method, augmented by the application of asymptotic waveform evaluation (AWE) technique is analyzed in the context of the application to radiation problems. Both ... -
Linear Phase Second Order Recursive Digital Integrators and Differentiators
(Společnost pro radioelektronické inženýrství, 2012-06)In this paper, design of linear phase second order recursive digital integrators and differentiators is discussed. New second order integrators have been designed by using Genetic Algorithm (GA) optimization method. ... -
Hybrid Coding Technique for Pulse Detection in an Optical Time Domain Reflectometer
(Společnost pro radioelektronické inženýrství, 2012-06)The paper introduces a novel hybrid coding technique for improved pulse detection in an optical time domain reflectometer. The hybrid schemes combines Simplex codes with signal averaging to articulate a very sophisticated ...
