Objective: To assess the implementation effects of clinical pathways, compared with usual care, among patients with stroke. Methods:Two investigators independently searched PubMed, Embase, the Cochrane Library, Web of Science, Chinese Biomedical Literature Database and Wanfang Database for studies published before December 2014. Jadad methodological approach was applied to assess the quality of...

This paper presents a novel coplanar waveguide (CPW) dual pass band and triple pass band filter using the split-modes of the loaded stub square loop resonators. With the CPW feeding line, two micro strip stub resonators built on the rear sides are used to suppress resonance. We have designed our filter on the FR4 substrate (permittivity = 4. 4 and loss tangent=0. 02) with 20x50mm square and thi...

A novel coplanar waveguide (CPW) fed wide tapered slot antenna (WTSA) is presented in this paper. A wideband CPW-towide slotline (WSL) transition is employed to feed the antenna. The corrugated edge structure and broken line tapered profile are also applied in this design to achieve wideband performance, as well as maintain compact size. A prototype of the antenna is fabricated. The measured re...

Abstract—A planar, circular monopole antenna (PCMA) with satisfactory radiation characteristics over an ultra-broadband is demonstrated. Compared to the classical coplanar-waveguide (CPW) fed PCMA, the radiation characteristics of the proposed CPW-fed PCMA are significantly improved, particularly at the frequencies around the higher band edge. This improvement is achieved by exploiting a tapere...

In this paper we proposed the estimation of the characteristic impedance, effect of dispersion, and the effective dielectric constant of Coplanar Waveguide (CPW) using conformal mapping theory and performances are analyzed. Numerically efficient and accurate formulae based on the conformal mapping method for the analysis of coplanar waveguide structures are presented. The analysis formulas for ...

A novel on-chip RF choke at 5 GHz is designed and measured for a class A operating Wireless LAN RF power amplifier (PA). The coplanar waveguide (CPW) based on-chip RF choke is implemented as an alternative component to inductors provided by the 0.35 μm SiGe BiCMOS technology. The CPW RF choke is designed at 5 GHz, and has a length of 1600 um and loaded with a capacitance of 0.95 pF. The measure...

A novel compact CPW-fed printed dipole antenna is proposed for dual-band Ultra wide band (UHF) RFID and wireless local area network (WLAN) operations. This antenna consist of two dipole elements and it covers 2.53 GHz Ultra High Frequency (UHF) RFID and 5.2 GHZ WLAN IEEE 802.11 Standards. The return loss, radiation pattern, field pattern, linear and circular polarization components are simulate...

We report on a metamolecule antenna, based on a fish-scale design but augmented with two split-ring resonators (SRRs) placed within the fish-scale loops. The properties of the antenna resonator, with and without additional SRRs, were examined using finite element method simulations (COMSOL Multiphysics). The simulation findings were subsequently confirmed experimentally, using a vector network ...
