A Simple Method to Enhance Gain and Isolation of MIMO Antennas Simultaneously Based on Metamaterial Structures for Millimeter-Wave Applications
Research overview
A compact 30 GHz MIMO antenna uses sigma-shaped metamaterial cells to improve gain and reduce coupling between closely spaced elements. The paper reports gain improvement above 8 dB and isolation improvement above 32 dB, with radiation efficiency of 68% at 30 GHz.
