Abstract :
A novel wideband design of a Ka-band compact dual polarized horn is presented. In order to suppress multimode affection, a novel multimode conical horn replaces conical horn. The simulated 10dB return loss bandwidth is approximately 15.6% (ranging from 29.5 to 34.5GHz). The simulated insertion loss of the orthomode transducer is less than -0.15dB, the isolation less than -55dB, and the VS WR is less than 1.3 in the operating frequency (ranging from 31 to 33GHz). This structure has properties of not only a wide band, ultra-low insertion loss and high isolation, but also good impedance match, small size, and radiation pattern. A prototype has been manufactured and measured. Since the simulated results are consisted with the measured ones, this novel compact structure has enormous potential for the dual polarized antenna.
