摘要：A dual polarized horn antenna that increases the efficiency of a square orrectangular aperture which may be used in situations where a high efficiency aperture isneeded in a constrained space. The antenna has a body that is tapered from a first end toa second end, wherein the first end is smaller in cross section than the second end. A

flange is formed around the periphery of the body adjacent to the first end. An openingis formed in the first end of the body. A tuning iris is preferably disposed in the openingthat provides for impedance matching. An insert is disposed in the central taperedopening adjacent to the second end that has a central cross-shaped tapered member.The central cross-shaped tapered member extends into the central tapered opening andforms a plurality waveguide passages that form a corresponding plurality of quadrants. Aplurality of cross-shaped members are respectively disposed in the quadrants andextend a short distance into the central tapered opening. The antenna may beadvantageously used where longer apertures are desired. The antenna has a radiatingefficiency on the order of 97 percent.
