Description
Summary:	This communication presents a novel Two-port Ka-band antenna design with improved isolation, high gain, and wide bandwidth for 5G applications. The suggested design employs a diamond-shaped dense dielectric (DD) antenna as a source with an X-slot mounted on a substrate that is fully grounded. An elliptical dielectric lens was made with Rogers RT5880 to improve the gain placed above the source (DD). This novel design enhances the gain bandwidth and decoupling between ports, delivering isolation levels over 20 dB and gain exceeding 12 dBi. The design achieves this without adding to the antenna profile or incorporating intricate decoupling structures. This makes it a highly promising approach for millimeter-wave MIMO communication services.
