Diversity/MIMO Antenna Incorporating Electromagnetic Band Gap Structures for Isolation

摘要

≤ -10 dB, over entire frequency band from 3 to 12 GHz. Enhanced isolation is achieved with an electromagnetic band gap (EBG) decoupling structure with circular and rectangular stubs is designed to achieve isolation between MIMO elements. This EBG structure provides an isolation of more than 22 dB for whole UWB frequency band. The UWB MIMO antenna array proposed in this paper has dimensions of 22 × 55 mm
