FREQUENCY SELECTOR FOR MM-WAVE COMMUNICATION USING A DIELECTRIC WAVEGUIDE

摘要

In described examples, signals on a dielectric waveguide (230) are filtered to pass or block selected frequencies. A combined signal is received in the dielectric waveguide (230). The combined signal includes at least a first frequency signal with a first wavelength and a second frequency signal with a second wavelength. The combined signal is split (231) into a first portion (path 1) and a second portion (path 2). The first portion of the combined signal is delayed by an amount of delay time (232) to form a delayed first portion. The delayed first portion is joined with the received combined signal to form a filtered signal, such that the first frequency signal is enhanced by constructive interference while the second frequency signal is diminished by destructive interference. A portion of the filtered signal is provided (233) to a receiver. The amplitude of the second frequency signal is attenuated in the filtered signal.
