In this study, Salmonella Typhimurium bacteria removal from polluted water has been investigated using multiwall carbon nanotubes arrays. Experimental results reveal that the contact time, the bacterial concentration and the weight of multiwall carbon nanotubes arrays have positive significant effects on the bacteria removal efficiency. Increasing the contact time and the weight of multiwall ca...

A design of back-to-back tapered line transition is presented. The transition is suitable for application in feeding arrays of double-side printed antennas. Tapered transmission lines are transmission line whose characteristic impedance is tapered from one value to another. Back-to-back circuits of identical transitions are designed, measured, and their characteristics are compared with theoret...

The progressive improvement of the feed networks and the continuous reduction of their cost have permitted the usage of nonuniform antenna arrays with fewer difficulties. One of the promising methods for the design of the above nonuniform antenna arrays is the Orthogonal Method (OM). ORAMA is a computer tool based on OM and designed for synthesis of linear antenna arrays on the Microsoft Window...

In this paper, a new method is proposed for calibrating a planar array of general geometry with respect to errors in location, phase and gain, even when all errors are present simultaneously (global calibration). The method requires the use of three pilot sources, which operate one at a time and from at least two different azimuth angles. Since the sources need not operate simultaneously, one o...

Abstract In this paper, we present a 28 GHz antenna array in package which covers the n257 and n258 frequency bands designated for 5G applications. The dipole is placed on one of two re-distribution layers fan-out eWLB (embedded Wafer Level Ball Grid Array) package. For TX RX, separate but identical arrays are each side die. paper presents novel horn-shaped heatsink not only dissipates heat, al...
