The effects of source directivity in various scenarios are also considered.
equivalence means that equivalent products must provide the same usable frequency range, receiving sensitivity and horizontal directivity
To maximise light transmission and precise beam directivity, optical fibres are incorporated to enable unprecedented >150 lumen CW output, with sharp narrow edges, resulting in enhanced vision that provides faster processing and more reliable monitoring on the manufacturing floor, and improved diagnostics and patient outcome in medicine.
The NEC 5G base station was equipped with a Massive MIMO antenna, which forms beams (directivity) that concentrate power on the location and direction of the 5G mobile station.
Buildings in proximity to the fault rupture and fault-rupture directivity zone were found to be at greater risk of damage from the earthquakes.
It covers a frequency range of 500kHz to 62MHz, has a directivity of 42dB (typ), a dynamic range of 74dB and a noise floor of 88dBm.
The obtained maximum directivity is 12.88 dBi at 10 GHz, which corresponds to a directivity increase of 5.71 dB with respect to an open-ended waveguide with the same aperture size as the feeder of the proposed lens antenna, as can be observed in Figure 13.
Seeing my past shame reflected in my undergraduate colleagues, I implemented a small study to investigate whether students in this center were feeling guilt about their tutoring styles, and if they were, whether that guilt was connected to a fear of directivity.
It is seen that the directivity index increases as frequency increases.
A simple low profile antenna for Vehicle-to-Vehicle (V2V) and Vehicle-to-Infrastructure (V2I) communications is needed; however, the necessity of high directivity antenna should be considered to ensure connectivity in different propagation channels.
If the static ground displacement is removed from the strike-normal component, there remains a large directivity pulse.
Further, electromagnetic, magnetostrictive, and piezoelectric ultrasound sources seem incapable of generating high power ultrasounds with good efficiency and directivity as they cannot undergo large longitudinal vibration amplitude.
