HORN ANTENNA

摘要

Horn antenna for transmission of microwaves comprising a conical horn (2), for directional transmission and reception of microwaves, and at the center of the horn's narrowest part, a transition piece (3) separating a wave guide from the environment. The transition piece (3) is tapered and is characterized by its tapering part (3a) being arranged so as to operate outside a normally fluid-filled circular space (4) between the horn (2) and the transition piece (3), so that the fluid in the space (4) does not affect the transmission of microwaves through the transition piece (3).
