摘要：
This paper presents an Input Array and an Output Array with a 1mm gap of high isolation in multiple input multiple output (MIMO) system by loading ceramic dielectric layer above magnetoelectric (ME) dipole antenna arrays. The decoupled array expands the bandwidth by adding metal walls, with a voltage standing wave ratio (VSWR) of less than 3 within 6.8 to 8.5GHz, and the isolation is increased to more than 20dB throughout the working frequency band. Besides, the ceramic dielectric layer does not excessively distort the array radiation patterns.
