Increasing return loss corresponds to lower SWR. Return loss is a measure of how well devices or lines are matched. A match is good if the return loss is high. A high return loss is desirable and results in a lower insertion loss. From a certain perspective 'Return Loss' is a misnomer. The usual function of a transmission line is to convey ...
Antenna directivity is the ratio of maximum radiation intensity (power per unit surface) radiated by the antenna in the maximum direction divided by the intensity radiated by a hypothetical isotropic antenna radiating the same total power as that antenna. For example, a hypothetical antenna which had a radiated pattern of a hemisphere (1/2 ...
In real systems, relatively little loss is due to mismatch loss and is often on the order of 1dB [dubious – discuss]. According to Walter Maxwell [2] mismatch does not result in any loss ("wasted" signal), except through the transmission line. This is because the signal reflected from the load is transmitted back to the source, where it is re ...
where L50 is the 50th percentile (i.e., median) value of propagation path loss, LF is the free space propagation loss, A mu is the median attenuation relative to free space, G(hte) is the base station antenna height gain factor, G(hre) is the mobile antenna height gain factor, and G AREA is the gain due to the type of environment. Note that the ...
Fresh inflation data released Wednesday is likely to keep the Federal Reserve on pause during its next policy meeting this month, even though a new reading did show some signs of easing.
Although the U.S. flag is at half-staff to mark the death of President Jimmy Carter, 8 Republican-led states will raise flags for Trump's inauguration
House Speaker Mike Johnson informed Republicans at a closed-door meeting Saturday that Donald Trump favored moving his agenda as one sweeping package, according to sources in attendance — a key ...
Ruze's equation is an equation relating the gain of an antenna to the root mean square (RMS) of the antenna's random surface errors. The equation was originally developed for parabolic reflector antennas, and later extended to phased arrays. The equation is named after John Ruze, who introduced the equation in a paper he wrote in 1952. [1]
