An L/C dual-band dual-polarized (DBDP) shared aperture microstrip array is proposed in the paper. In the array, the novel sandwiched stacked patch structure is proposed and employed to improve lower band bandwidth for given antenna thickness. Several key issues regarding the proposed structure are discussed, including: 1) merits of proposed sandwiched stacked patch structure; 2) C-band feeding method; 3) radiation performance in both bands. A prototype array of L/C DBDP sandwiched stacked patch
