Abstract
A quad-element multiple-input-multiple-output (MIMO) antenna with ultra-wideband (UWB) performance is presented in this paper. The MIMO antenna consists of four orthogonally arranged microstrip line-fed hexagonal monopole radiators and a modified ground plane. In addition, E-shaped and G-shaped stubs are added to the radiator to achieve additional resonances at 1.5 GHz and 2.45 GHz. The reliability of the antenna in the automotive environment is investigated, with housing effects taken into account. The housing effects show that the antenna performs consistently even in the presence of a large metal object. The proposed MIMO antenna has potential for various automotive applications, including vehicle-to-vehicle (V2V), vehicle-to-infrastructure (V2I), vehicle-to-everything (V2X), intelligent transport system (ITS), automatic vehicle identifier, and RFID-based electronic toll collection.

Summary
The quest for high data rates has led to increased research into ultra-wideband (UWB). In [14,15,16,17], dual-port MIMO/diversity antennas with split-ring resonators (SRRs) were presented with improved isolation. An antenna working at multiple frequencies was presented in [22], where the resonating elements were arranged orthogonally to each other to reduce coupling between them. In [24], a quad-port multiband MIMO antenna with pattern diversity and low inter-element coupling was reported. The MIMO antenna is compact in size, covers multiple frequency bands, and offers good reliability in the automotive environment. It can be integrated into a vehicle using the shark fin mounting available in the market. The diversity parameters are evaluated to understand the performance of the MIMO antenna, and the results are satisfactory
