The directivity of the coupler that forms the heart of a directional power meter is critical to the accuracy of these measurements.
For example, the directivity performance determines how well the coupler in the measurement system separates the reflected signal from the incident.
The configurable BTE has the highest possible directivity available in a BTE hearing aid," said Christensen.
The achieved directivity of this proposed array antenna varied from 7.
In case of ILA with large extension, the use of the absorber can increase the directivity by several decibels, e.
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).
Directivity pattern is one of the most important characteristics of the speaker in the design process which is defined based on the required SPL distribution from the customer.
One way to increase the directivity is to design an array of microstrip patch elements; however, designing an array of elements require feeding network which might complicate the design and occupy more design space.
The term "directivity pulse" usually refers to "forward directivity pulses", which are more critical to engineered structures (Cox and Ashford, 2002).
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.
In this way, the antenna array directivity is increased compared to a regular directional antenna array.
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.
