A quadband filter for 1.57 GHz GPS, 5.2 GHz WLAN and 3.5 GHz Worldwide Interoperability Microwave Access is designed and tested in this work. A compact Defected Ground Structure (DGS) quad-band microstrip Band Pass Filter, stub loaded Low Pass Filter, short circuited uniform impedance resonator and ring resonator are used to maintain the size and performance. Use of stub resonator at central po...

We propose a submicron plasmonic wavelength filtering/demultiplexing structure based on aperture-coupled slot cavities, which can overcome the limitation by the field skin depth of ∼25nm in a conventional evanescentcoupling approach, and thus lead to an easy-to-fabricate device structure. By introducing the stub-induced interference arm in the drop or bus waveguide, the power ratio between the ...

JavaScript is expected to be a programming language of even wider use, considering demands for more interactive web/mobile applications. While reliability of JavaScript code will be of more importance, testing techniques for the language remain insufficient compared to other languages. We propose a technique to automatically generate high-coverage unit tests for JavaScript code. The technique m...

© 2013 ETRI Journal, Volume 35, Number 2, April 2013 This letter presents a compact dual-mode tri-band bandpass filter by using a short-circuited stub-loaded stepped-impedance resonator (SIR) and a short-circuited stub-loaded uniform impedance resonator. Also, a hairpin SIR geometry is introduced to miniature the size of this filter while maintaining excellent performance. The use of a short-ci...

a r t i c l e i n f o Keywords: Concrete-filled steel tube (CFST) Confinement effect Fuzzy logic Modified learning from example (MLFE) Axial load capacity A circular concrete-filled steel tube (CFST) has several advantages compared with the conventional reinforced concrete member or hollow steel tube, since the tri-axial state of compression of the concrete infill increases its strength and str...

We examined the microtubule-binding domain of the microtubule-associated protein (MAP), MAP-2, using rabbit antibodies that specifically bind to the microtubule-binding region ("stub") and the projection portion ("arm") of MAP-2. We found that (a) microtubules decorated with arm antibody look similar to those labeled with whole unfractionated MAP antibody, though microtubules are not labeled wi...

This paper presents a multiband CPW-fed slot antenna with L-slot bowtie tuning stub. The proposed antenna has been designed for PCS 1900, UMTS, WLAN 802.11 a/b/g and bluetooth applications, with a cost-effective FR4 substrate. The proposed antenna still radiate as omni-directional in azimuth plane and sufficient bandwidth for all above mentions. The proposed antenna works as dual-wideband, band...

A printed slot antenna fed by a microstrip line with a diamond-shaped tuning stub for bandwidth enhancement is proposed and experimentally validated. Impedance bandwidth, radiation pattern, and gain characteristics of the proposed antenna are investigated. The simulated results show that the impedance matching of the proposed rotated slot antenna is greatly affected by the dimension of the slot...
