A bow-tie slot antenna with tapered connection to a 50Ω coplanar waveguide (CPW) feed line is introduced and its dimensional parameters have been studied for wideband operations in the X-band. A set of two element bow-tie slot antennas fed by one CPW is also introduced for wider bandwidth and improved gain. The configuration of one CPW feeding two elements of this antenna is simulated and it ac...

The memory bandwidth demands of modern microprocessors require the use of a multi-ported cache to achieve peak performance. However, multi-ported caches are costly to implement. In this paper we propose techniques for improving the bandwidth of a single cache port by using additional buffering in the processor, and by taking maximum advantage of a wider cache port. We evaluate these techniques ...

We propose a new method to construct confidence intervals for spectral mean and related ratio statistics of a stationary process, that avoids direct estimation of their asymptotic variances. By introducing a bandwidth, a self-normalization procedure is adopted and the distribution of the new statistic is asymptotically nuisance-parameter free. The bandwidth is chosen using information criteria ...

A microstrip-fed printed bow-tie antenna is presented in order to achieve wide bandwidth, high gain, and size reduction. A comparison between the bow-tie and the quasi-Yagi (dipole and director) antennas shows that the bow-tie antenna has a wider bandwidth, higher gain, lower front-to-back ratio, lower cross-polarization level, and smaller size. Two-element arrays are designed and their charact...

1. Abstract In this design, the dual band dipole antenna feed network with wide bandwidth tapered microstrip balun is studied. The design and experimental results of low profile embedded microstrip dipole antenna with tapered microstrip balun shows fairly good performances. The feed network of the design with wider bandwidth and lower power loss tapered microstrip line to overlap coplanar strip...

A single stage quadrature hybrid coupler with enhanced flat balance over a wide bandwidth is presented in this article. The present coupler is realized by replacing the transmission line sections of the conventional two-branch coupler by their equivalent parallel coupled microstrip lines (PCML). The impedance controlled wide-bandpass response produced by the PCML is utilized to achieve flat bal...

Preemption is a traffic engineering technique in Multiprotocol Switching Networks that enables creation of high priority paths when there is not enough free bandwidth left on the route. Challenging part of any preemption method is to select the best set of paths for removal. Several heuristic methods are available but no wider comparison had been published before. In this paper, we discuss the ...

Mixed H2/H∞ method is proposed to design a controller for flexible joint robots (FJR) considering actuator saturation. By considering the control action in the mixed sensitivity function one can reduce the amplitude of the control action but this may affect all frequencies. A more advanced method based on frequency weighting of the control action contribution in the mixed sensitivity function i...

A CMOS image sensor that employs a vertically integrated double junction photodiode structure is presented. This allows colour imaging with only two, wider bandwidth, filters. The sensor uses a 184 x 154 6-transistor pixel array at a 9.6 μm pitch. Results of the device characterisation, and colour image reconstruction using the prototype sensor, are presented.

We report ultra-broadband supercontinuum generation in high-confinement Si3N4 integrated optical waveguides. The spectrum extends through the visible (from 470 nm) to the infrared spectral range (2130 nm) comprising a spectral bandwidth wider than 495 THz, which is the widest supercontinuum spectrum generated on a chip.
