In this paper, we present a miniaturized, Ultra Wide Band (UWB) elliptical slot antenna with a circular stub as a tuning element printed on a FR4 substrate with a dielectric constant of 4.4 operating in the frequency range from 2 GHz up to 14 GHz over which the return loss below -10 dB. The antenna is intended to operate in a system designed to assist the visually impaired in indoor navigation ...

This paper presents improved quad-mode resonators based on the open/short-end load of center stub, which introduces self-coupled structure. Compared with traditional stub-loaded stepped impedance resonator (SLSIR), proposed can significantly reduce circuit size and further increase design freedom. First all, a comprehensive theoretical analysis is performed to infer resonant characteristics res...

A system for dynamic compilation under the Unix operating system is described. The basis of the system is an incremental assembler that can be used statically or during program execution to insert or replace a module in an executable image. All cross-module references are via offsets into a run-time symbol table. All generated code is independent of its location or the location of the symbol ta...

This paper presents a study on the effect of impedance mismatch on phase linearity (group delay variations) in grounded coplanar waveguide (GCPW) structures. Two 400 ps GCPW delay lines were designed using a short circuited stub and a transmission line. The structures were simulated over a wide frequency range (0.1 GHz5 GHz) using both ADS circuit model and CST electromagnetic simulation tool. ...

After classifying internetworks into type internetworks, protocol internetworks, and organization internetworks, this paper focuses on the last of these. A key problem with organization internetworking is global routing scalability. In developing the NEI architecture to address this problem, some basic mechanisms/tenets of IP internetworking are upended. In NEI, internetworking addresses are no...

We propose two novel low-pass filter (LPF) structures that have generated additional attenuation poles from applying spur-lines to typical open-stub LPFs. The first structure has the added serial lines, and second parallel open stub. From characteristic analyses of filters with proposed design, it was confirmed length spur-line an important variable for controlling stopband bandwidth depth. typ...

In recent years, the introduction of new indoor communication wireless protocols such as Bluetooth, IEEE 802.11b, and wireless local area networks (WLANs) has led to enormous challenges with respect to antenna designs for wireless communications. The newer WLANs, however, have to provide high-speed wireless connectivity between PCs, laptops, and other equipment in corporate, public, and home en...

We study transport through a single channel T -stub geometry strongly coupled to a superconducting reservoir. In contrast to the standard stub geometry which has both transmission resonances and anti-resonances in the coherent limit, we find that due to the proximity effect, this geometry shows neither a T = 1 resonance (T is the transmission probability for electrons incident on the T -stub) n...

A broadband microstrip bandpass filter (BPF) with compact size, sharp skirt and wide upperstopband performance is proposed using the triple-mode stub-loaded resonator. The resonator can generate one odd mode and two even modes in the desired passband. Due to the main path signal counteraction, two transmission zeros Tz1, Tz2 can be created near the passband edge to achieve sharp skirt. Two tran...
