Cross Polarized Antenna System for 5G Wireless Applications

A novel cross-polarized compact antenna system is described for Ultra-Wide Band communication systems. It also includes the sub-6 GHz spectrum for the initial 5G deployment. The complete antenna system is a unique configuration of Multiple Input Multiple Output (MIMO) antennas that cover the RF band from 2 GHz to 12 GHz. This MIMO system is made up of two F-shaped monopoles with slotted fractured ground planes. A 90-degree difference between back-to-back antennas is constructed. The entire volume of the MIMO antenna system is 14 mm × 14 mm × 0.25 mm. Its broad compact structure makes it ideal for mobile phones and much other hand-held equipment. The maximum amplification reported was 4.8 dB, and the measured far field patterns were nearly isotropic. The Envelope Correlation Coefficient (ECC) and Gain Diversity of the proposed MIMO antenna system are shown.
