Antenna Tracking System: Having acquired a target through a scanning method as just described, it may then be necessary to locate it very accurately, perhaps in order to bring weapons…
Antenna Scanning Methods: Radar antennas are often made to scan a given area of the surrounding space, but the actual scanning pattern depends on the application. Figure 16-6 shows some…
Wideband Antenna Types: It is often desirable to have an antenna capable of operating over a wide frequency range. This may occur because a number of widely spaced channels are…
Antennas in Electronic Communication Articles: Antenna Definition: The Antenna Definition is a quick review of impedance matching (basic transformer theory) and resonant circuits. It was pointed out that maximum power…
Lens Antenna Design: The paraboloid reflector is one example of how optical principles may be applied to microwave lens antenna, and the Lens Antenna is yet another. It is used…
Horn Antenna Design: Horn Antenna Design - As we know, a waveguide is capable of radiating energy into open space if it is suitably excited at one end and open…
Parabolic Antenna: The Parabolic Antenna is a plane curve, defined as the locus of a point which moves so that its distance from another point (called the focus) plus its…
Directional High Frequency Antenna: Directional High Frequency Antenna are likely to differ from lower-frequency ones for two reasons. These are the HF transmission/reception requirements and the ability to meet them.…
