Different sources … Meer weergeven The short wavelengths of microwaves allow omnidirectional antennas for portable devices to be made very small, from 1 to 20 centimeters long, so microwave frequencies … Meer weergeven The term microwave also has a more technical meaning in electromagnetics and circuit theory. Apparatus and techniques may be … Meer weergeven Microwave technology is extensively used for point-to-point telecommunications (i.e., non-broadcast uses). Microwaves are especially suitable for this use since they are more easily focused into narrower beams than radio waves, allowing frequency reuse Meer weergeven Microwaves travel solely by line-of-sight paths; unlike lower frequency radio waves, they do not travel as ground waves which follow the contour of the Earth, or reflect off the ionosphere (skywaves). Although at the low end of the band they can pass through … Meer weergeven High-power microwave sources use specialized vacuum tubes to generate microwaves. These devices operate on different … Meer weergeven Bands of frequencies in the microwave spectrum are designated by letters. Unfortunately, there are several incompatible band designation systems, and even … Meer weergeven
