Abstract
Disclosed are exemplary embodiments of multiband multiple input multiple output (MIMO) vehicular antenna assemblies for installation to a vehicle body wall. In exemplary embodiments, a multiband MIMO vehicular antenna assembly generally includes at least one cellular antenna configured to be operable over one or more cellular frequencies (e.g., Long Term Evolution (LTE), etc.), at least one satellite antenna configured to be operable over one or more satellite frequencies (e.g., Global Navigation Satellite System (GNSS), satellite digital audio radio services (SDARS), etc.) and at least one Dedicated Short Range Communication (DSRC) antenna configured to be operable over DSRC frequencies.
