Stereo Antenna Patterns from Principal Plane Patterns.
NAVAL WEAPONS LAB DAHLGREN VA
Pagination or Media Count:
In most antenna applications, it is sufficient to consider antenna patterns in two dimensions only, mostly the two-dimensional patterns in the principal planes. When antennas are considered from the electromagnetic compatibility EMC and electronic countermeasures ECM point of view, the STEREO-three-dimensional patterns become of interest. The question then arises whether it is possible to obtain the gain in an arbitrary direction from the gain patterns as measured in the two principal planes. The report answers this question in the affirmative for rectangular apertures and in the angular region around the antenna where its pattern is adequately represented by an aperture integral. Author
