MIMO Antenna System With Pattern Diversity for Sub-6 GHz Mobile Phone Applications
A MIMO antenna system is designed and presented for sub-6 GHz mobile phone applications. The proposed antenna design consists of six loop-type radiation elements. From the six elements, four elements are placed at the corners of the mobile phone PCB by following pattern diversity configuration, whil...
