摘要
A novel structure combined of an I-shaped microstrip line and eight slots etched from the ground plane is proposed to decouple both E-plane and H-plane antenna arrays. Five types of antenna arrays at 5.25 GHz with different linear placements are discussed for the first time and the decoupling structure is valid to them all. The edge-to-edge distances of the H-plane arrays and the E-plane arrays are 0.09 0 and 0.17 0(,) respectively. Simulated and measured results indicate that the combined structure can effectively reduce the mutual coupling, with the maximum values reaching to 22.62, 28.41, 21.04, 22.33, and 26.04 dB for five types, respectively. The proposed structure is potential in the application of multielement arrays and communication MIMO system.
