This letter presents a compact dual-polarization quad-ridge conical horn (DPQRH) antenna. Different from classical solutions, the proposed antenna adopts a nonuniform step ridge profile. One of the main novelty of the antenna is the feeding system, a stripline-based orthomode transducer solution. Th...
