According to the radiation patterns depicted, typical antennas used in a three-sector base station have 66?of horizontal beamwidth.
32.
The far-field radiation pattern of an antenna is the sum of its near-field evanescent modes with high Q factor, where
33.
Where | W | ^ 2 is the radiation pattern from a single dipole at the metal / dielectric interface.
34.
Professor Edward L . Bowles set out to determine the signal strength and radiation patterns of different antenna arrays in 1926.
35.
In this case the reference antenna is built to have a high degree of repeatability in its radiation pattern and efficiency.
36.
Furthermore, control of the radio frequency or microwave radiation pattern is efficiently increased, and mutual coupling between antennas is also reduced.
37.
When a speaker is placed horizontally or even designed in a horizontal arrangement, the argument goes, the sound-radiation patterns become muddied.
38.
This states that the temperature surrounding the antenna is integrated over the entire sphere, and weighted by the antenna's radiation pattern.
39.
This illustrates the general principle that if the shape of an antenna is symmetrical, its radiation pattern will have the same symmetry.
40.
When so sectionalized the sections are themselves phased so as to provide the optimum vertical radiation pattern ( suppressing high-angle radiation ).
