摘要：
A dielectric-loaded dual-port monopole antenna system is proposed for multi-input multi-output (MIMO) applications. Two closely spaced monopole antennas are covered by an inverted dielectric cone. By introducing a dielectric-air boundary (DAB), the enclosing dielectric cone helps the inside electromagnetic fields redistribute when one monopole is excited. As a result, 'field valleys' may show up in the cone. If a second monopole is placed in a 'field valley' of the first monopole, their mutual coupling can be significantly suppressed. In this work, the simulated 35-dB coupling bandwidth can cover the band between 3.2 GHz and 3.75 GHz, which is sufficient for 5G sub-6GHz applications.
