ANGLE DIVERSITY SIGNAL SEPARATOR USING MODE CONVERSION

摘要

ANGLE DIVERSITY SIGNAL SEPARATOR USING MODE CONVERSION In an angle diversity receiving system, the primary and diversity signals are produced by a waveguide signal separator coupled to a single receiving antenna. The separator operates by converting selective higher order modes in the antenna into fundamental modes that will propagate in its two output waveguides. The result is a robust system that operates over a frequency band wide enough to cover both the 4GHz and 6GHz common carrier bands with both horizontally and vertically polarized signals, and that can use a wide variety of antennas.
