A compact missile-borne conformal array antenna with off-axis radiation

摘要

A missile-borne conformal array antenna with off-axis radiation is designed in this article. 16 inclined radiation elements are connected by a power divider to form a conformal array, which consists of an active patch and a parasitic patch with an open-circuit stub. By coplanar coupled feeding and adjusting the length of the open-circuit stub, the radiation pattern toward axis-direction of missile is realized. Experimental results show the antenna can cover 5.25-5.45 GHz with -10 dB return loss and with off-axis radiation. Due to its excellent electrical performance and conformal ability, it can be widely used on the missiles.
