The resulting structure improves the maximum
directivity with respect to the feeder along a large bandwidth (more than 5 dB) and provides a good crosspolar level (better than -35 dB).
This guilt manifested itself in two often combined ways: tutors felt guilty because they broke what they saw as a major "rule" of the writing center when they turned toward directive strategies, and/or they felt guilty because they worried their directive style had taken the focus off the client (essentially, I argue, they believed their
directivity was the antithesis of student-centeredness).
Accordingly, a nonlinear finite-element methodology (FEM) was first developed to study the tunnel behavior under the first mentioned effect of faulting (fault slip) and then to study under the combination of both effects (i.e., fault dislocation and dynamic ground movement due to rupture
directivity).
The radiations from different parts of a simple flat plate with constant thickness are in counter phase leading to phase cancellation and, therefore, poor
directivity. On the contrary, if one considers a plate with some steps on the surface raised half a wavelength of the radiated sound, the radiations become in-phase and
directivity increases.
High
directivity fractal boundary microstrip fractal boundary microstrip patch antenna presented by Borja et al [2] shows that a patch antenna with a fractal boundary exhibits localized modes.
The ZOR antenna can be designed much smaller than half a wavelength, enabling a very compact size [10,11], or much larger than half a wavelength, in order to reach high
directivity [12].
The work presented in this paper is an extension of previous work on the design of NFC passive antenna and exclusively discussed the simulation results for h- field, gain and
directivity to show that customized antenna is efficient enough to communicate with any active NFC device (Razi and Awais, 2014).
The algorithm if compared with the
directivity of currently used receiving antenna at mobile station, provide 5-8% less ISI effect.
Bruel & Kjaer's personnel will characterize the individual noise sources of the Eurofighter and measure their
directivity under the different thrust and flight configurations.
Antennas used for the free-space technique have high
directivity and satisfy this requirement.
MHz to 40GHz, the Site Master S820E offers field technicians, engineers and wireless network installers dynamic range,
directivity, and durability so they can conduct accurate measurements in the installation, maintenance, and troubleshooting of microwave communications systems.
And
directivity refers to the fact that it is not arbitrary to switch from one state to another.
