Cover Story: Owing to increased device connectivity in the 5G environment, simultaneous multidevice communication is unavoidable and, therefore, high electromagnetic (EM) interferences may cause a significant degradation in device performances. To facilitate multidevice communication with a reliable interference rejection, an antenna supporting polarization diversity is required. Therefore, in this article, we propose a new compact antenna based on a crossed inverted-V structure, with a ground plane as the common reflector at 5.8 GHz. The proposed structure can generate four different types of polarizations (horizontal, vertical, right-handed, left-handed), and it can provide high directivities for all polarizations despite its compact size.
