A novel cassegrain antenna with an FSS sub-reflector and cylinder matcher

摘要

Mobile communication between two moving objects is interesting because of its application in military and navigation. Cassegrain antenna, which is high gain and narrow beam, is the most common construction in mobile communication. To reduce the difficulty of position due to narrow beam, an FSS is proposed to obtain wide beam at some frequencies. The disk sub-reflector is used to decrease the axial size and a cylinder matcher is proposed to solve the mismatch resulting from the disk. The model is constructed and simulated by CST and the result is the same to theory.
