In this paper we present a measurement technique for evaluation of antenna systems in car-to-infrastructure communication systems. The focus of this work was on small and cheap measurement devices that can be placed at different positions in a car or motorbike. With the new measurement process multiple antennas were evaluated simultaneously using a bandwidth of 20 MHz. That is, propagation characteristics for broadband communication like, for example, LTE communication can be analyzed. Antennas at several positions of a car were examined separately as well as by using maximum ratio combining.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
