Traditional helix antenna is firstly modified to radiate orbital angular momentum (OAM) wave, which has a compact size and an outstanding gain. Firstly, general principle of generating OAM by introduced. Secondly, field pattern electromagnetic distribution on are analyzed. Then, based the preceding analysis, dual-OAM-mode designed, fabricated, measured. Instead using traditional helical wire, this prototype realized PCB flexible dielectric laminate, rolled into hollow cylinder. This makes...
Abstract Right heart failure ( RHF ) is a serious health issue with increasing incidence and high mortality. ventricular assist devices RVADs have been used to support the end‐stage failing right ventricle RV ). Current operate in parallel native , which alter blood flow pattern increase afterload, associated tension cardiac muscles long‐term valve complications. We are developing an in‐series RVAD for better unloading. This article presents mathematical model compare effects of unloading...
A double-Orbital-Angular-Momentum (OAM)-mode microstrip antenna is designed, simulated, fabricated and measured, which generates OAM with mode number l = 2 3 on 5 GHz by two resistor loaded rings respectively. For existing antennas, structures like circular array, parabolic reflector electromagnetic meta-surface are widely adopted, electrically large hard to be integrated. However, the proposed has a compact size low profile, can integrated in RF circuit as component. To solve problem of...
Abstract A novel and feasible solution to generate plane spiral orbital angular momentum (PSOAM) vortex beam is proposed in this paper. The general principle of generating PSOAM circular antenna array (CAA) deduced, verified by the simulation dipole CAA. Four double-slot Vivaldi elements connect sequentially are inserted into a CAA, which makes easily fabricated fully miniaturized. Both simulated measured results show that it can with l = 3 ( mode number wave) at 5 GHz. phase observed, peak...
A novel doubled folded quarter mode substrate integrate waveguide (DFQMSIW) resonator based on low temperature co-fired ceramic(L TCC) is proposed, and a plane cascade connected DFQMSIW tunable filter design the resonator. The double-order realizes center frequency linearity, which works at 1.6GHz with adjustable range of 51.8% insertion loss 1.2dB, return less than -15dB. coplanar cavity coupling structure achieves bandwidth switchable.
This paper presents a high gain wideband omnidirectional COCO antenna array.The array operates at 1500MHz-2000MHz and can be used for mobile communication.The planar micro-strip is composed of seventeen trapezoidal patch antennas with different sizes.By loading matching resistance, the achieve an impedance bandwidth 28.5% VSWR<=2, it has good horizontal radiation characteristics.The out-of-roundness less than 0.3 dB highest 9dB.
Traditional helical antennas are modified to generate Orbital Angular Momentum (OAM). Compared with the poor gain or large sizes of most existing OAM antennas, proposed antenna realizes a sufficient within limited dimension, which makes it promising in practical application. As an example, prototype is designed and simulated, multiplexes <i xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">l</i> =2 3 on 5GHz (/ mode number), its total size about...
