The two-element design gives modest directivity (about 2.0 dB) with a null towards the rear of the antenna, yielding a high front-to-back ratio: Gain up to 9.7 dBi can be achieved at 28 MHz. [3] Because the placement and size of the parasitic reflector both depend highly on wavelength, each Moxon antenna functions properly on the frequency band ...
The actual result is 34.6380 dBi, just shy of the ideal 35.0745 dBi we expected. [7] Why the difference from the ideal? If the spacing in the x and y dimensions is λ {\displaystyle \lambda } , then the spacing along the diagonals is λ 2 {\displaystyle \lambda {\sqrt {2}}} , thus creating tiny regions in the overall array where photons are ...
For the commonly utilized half-wave dipole, the particular formulation works out to the following, including its decibel equivalency, expressed as dBi (decibels referenced to isotropic radiator): R λ 2 = 60 Cin ( 2 π ) = 60 [ ln ( 2 π ) + γ − Ci ( 2 π ) ] = 120 ∫ 0 π 2 cos ( π 2 cos θ ) 2 sin θ d θ , = 15 ...
Slotted array UHF television broadcasting antenna. As shown by H. G. Booker in 1946, from Babinet's principle in optics a slot in a metal plate or waveguide has the same radiation pattern as a driven rod antenna whose rod is the same shape as the slot, with the exception that the electric field and magnetic field directions are interchanged; the antenna is a magnetic dipole instead of an ...
Los Angeles Chargers quarterback Justin Herbert exited his team's Week 14 "Sunday Night Football" appearance early with an apparent leg injury.
In 40 years of explosive population, spending and debt growth, the size of the federal workforce has stayed pretty much the same. Wait, exactly how many people work for the federal government ...
