In this article, a novel and simple dual-frequency Wilkinson power divider is proposed. Considering that there only one section of transmission line linking the input port output directly as part transformer, very compact. To satisfy characteristic, traditional quarter-wavelength transformer replaced by structure which consists parallel stub at port. Besides, in order to obtain ideal isolation with keeping matching ports, resistorr R series LC components are added. Furthermore, closed-form...
Abstract An alpha particle detector with high energy resolution is highly desired in the fundamental field of high-energy physics and various applications environmental monitoring. In this paper, an excellent 0.35% for 5486 keV α-particles from 241Am charge collection efficiency 98.5% achieved by a passivated implanted planar silicon window area 530 mm². High attributed to crystalline quality long carrier lifetime, indicating less scattering charges defects suppression randomness signal...
The electroneutrality assumption has long been adopted by scholars; however, this may lead to an oversight of certain physical effects. Using derivations from a discontinuous medium, we have obtained expression for the potential and energy many-body unipolar charge system, which corresponds well its counterpart in continuous medium. compressed form suggests that compressing macroscale charged body nanoscale can yield enormous electric energy, thereby establishing concrete research framework...
A novel Wilkinson power divider operating at arbitrary dual-frequency (namely dual band) with unequal dividing ratio is proposed here. The asymmetric structure that consists of seven sections transmission lines different characteristics impedances given to satisfy the and matching characteristic. To obtain ideal isolation, a series resistor–inductor–capacitor (RLC) applied. Furthermore, closed-form design equations are derived based on circuit theory line theory. Finally, calculation,...
The technique of dual transmission lines is applied to replace quarter wave transformers for a compact Bagley polygon power divider. developed divider not only can be easily fabricated on the planar printed circuit board without lumped element, but also has characteristics size and wide bandwidth. For verification, proposed three‐way microstrip designed at 2.0 GHz. Simulated measured frequency responses both validate with lines. Furthermore, occupies 23% conventional one.
A simple coupled-line circuit configuration is proposed to design microstrip bandpass filter with sharp skirt selectivity in this paper. This novel consists of two-section coupled lines a common connected point. An equivalent odd-mode and even-mode analysis applied analyze transmission reflection property, the effective analytical scattering parameters' expressions are achieved. Design curves for given while six typical numerical examples presented. The presented simulation results show that...
In this paper, a dual-band CPW-fed MIMO antenna is designed and analyzed. Fundamental resonance of the coplanar stepped impedance resonator (CSIR) produces 1 <sup xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">st</sup> operating band, while its harmonic rectangular slot line (RSLR) construct 2 xmlns:xlink="http://www.w3.org/1999/xlink">nd</sup> band. The port-to-port isolation within band high since it works at resonant frequency CSIR. bandwidth can...
