A distinctive low-profile 2x2 MIMO antenna system for Wi-Fi 7 applications is presented in this paper that is compact, easily manufactured and with excellent performance. Due to its physical properties and RF performance, the design can be placed in hidden locations for various applications such as the automotive field in the front side mirrors or front dashboard, and consumer products in laptops and internet wireless routers.
Various multiple-input multiple-output (MIMO) antenna systems are presented in this paper using low profile wideband Planar Inverted-F antenna (PIFA) and compact wideband monopole for automotive application in the sub-6GHz 5G systems and Vehicle-to-Everything (V2X) communications that operate on the frequency range from 617MHz to 6GHz. The envelope correlation coefficient (ECC) and diversity gain (DG) are calculated in each MIMO configuration as they represent the two key factors in the MIMO performance.
