The resistive loss of a coaxial cable is caused by several things; impedance of the conductor, and the type of dielectric material used and the skin effect and causes the signal to be attenuated. In this research, various comparison was made on different coaxial cables in other to test their resistivity per length of the conductor and measure the losses per meter of the coaxial cables. The various properties of the conductor, the impedance, capacitance, and the velocity of propagations was taken into consideration. Measurements were carried out to derive our data, and MATLAB was used in analyzing the results and the behaviour of the LMR series, RG8, RG6A, Davis RF, and CQ110 coaxial cables. Based on the findings, it is concluded that for a better and improved signal quality and to reduce resistive losses in coaxial cables, the characteristic impedance of the cable should be 80 ohms as this will reduce the coaxial cable resistive losses.</p> Promise Elechi Oguejiofo Obeta Copyright (c) 2021 World Journal of Electrical and Electronic Engineering 2022-06-09 2022-06-09 11 24 Experimental Study of Winding Topology Effect on Coils Electrical Behavior https://www.scipublications.com/journal/index.php/wjeee/article/view/469 <p>The main goal of this paper is to study the effect of winding topology on coils electrical behavior in experimental way to take into account the self capacitance of coils, several coils are fabricated using copper wire with changing the number of winding layers and fixing the spiral numbers, in addition two coils was fabricated to study the effect of the winding wire diameter, the measured reactance and resistance of eddy current coils are done using precision LCR-meter with a frequency range from 0Hz to 5 MHz, the experimental results shows very remarkable interactions of resonator due to the changing of winding topology and his effect on self capacitance of coils.</p> Safer Omar Adib Bensaid Samir Copyright (c) 2021 World Journal of Electrical and Electronic Engineering 2022-10-29 2022-10-29 15 21 A Moving Single-Station Doppler Ranging Solution by Means of Direction Finding Method https://www.scipublications.com/journal/index.php/wjeee/article/view/174 <p>The Doppler shift is an angle dependent function. Based on the relationship between frequency shift and angle, direction-finding method can be used directly to obtain the ranging solution based on frequency shift measurement. The Doppler ranging solution obtained by this method has excellent calculation accuracy and can keep the same accuracy as the ranging solution based on frequency shift difference processing.</p> Tao Yu Copyright (c) 2021 World Journal of Electrical and Electronic Engineering 2021-12-10 2021-12-10 1 10
