Measured probabilities of detection for 1- and 2 bitstreams of 2-port car-roof antenna in RIMP and Random-LOS 2016 (English)In: 2016 10th European Conference on Antennas and Propagation, EuCAP 2016, 2016Conference paper, Published paper (Refereed)

Abstract [en]

Autonomous cars will in a near future drive around in cities and on highways. Antennas will then be needed to secure the wireless connection to these cars. To be able to test the antennas we have defined two edge environments: the Random Line-of-Sight (LOS) and the Rich Isotropic Multipath (RIMP). This paper shows a throughput performance comparison between measurements and simulations of a car-roof (shark-fin) antenna mounted on a ground plane in both of these environments. The comparison is done for both one and two bitstreams in a 2×2 MIMO system. The analysis is based on probability of detection (PoD) curves representing the throughput performance with digital threshold receivers. © 2016 European Association of Antennas and Propagation.
