DUPLEXERS AND RELATED DEVICES FOR 5G/6G AND SUBSEQUENT PROTOCOLS AND FOR MM-WAVE AND TERAHERTZ APPLICATIONS

摘要

A ring resonator based T-shaped duplexer for use in communication systems includes a T-shaped microstrip duplexer body having a first rectangular-shaped body section and a second rectangular-shaped body section that extends from the first-rectangular shaped section in a perpendicular position relative to the first rectangular-shaped section, three connection ports including a first connection port disposed at an open end of the second rectangular-shaped body section, a second connection port disposed at one end of the first rectangular-shaped body section, and a third connection port disposed at another end of the first rectangular-shaped body section, and two bandpass filters, each comprising a ring resonator having a circular shape, an outer edge thereof being connected to the first rectangular-shaped body section, wherein each of the bandpass filters creates an Electromagnetically Induced Transparency window within a frequency absorption region of the filter to allow a signal to pass at a pre-tuned frequency band.
