Centered longitudinal shunt slot fed by a resonant offset ridge iris

摘要

A radiator (10) comprising one or more centered longitudinal shunt slots (12) disposed in a rectangular waveguide (11) that are fed by corresponding offset ridge resonant irises (14). The offset ridge resonant irises that are centered on each respective slot. When multiple slots and offset ridge resonant irises are employed, adjacent irises are oriented opposite to one another.
