“…The similarity grouping and averaging of the complex beamforming vectors v w and u w over time (over several locations of a mobile system) matches the antenna systems at the transmitter and at the receiver to the communication channel by emphasizing the important predominant spatial directions with higher gain and suppressing other directions. For the first time, the similarity grouping and averaging step is performed by applying the SVD over time, frequency and space dimensions here as this is a novelty compared to the work in [8]:…”

Abstract-In this paper a multiple input multiple output (MIMO) radio channel measurement system is presented that utilizes several software defined radio (SDR) platforms at the transmitter and at the receiver. The system hardware buildup and its calibration technique are presented. The channel measurement results are afterwards exploited for a special antenna synthesis method that was already proofed by raytracing channel simulations. The antenna synthesis method is applied to a mobile single and to a mobile multiple channel receiver. The resulting synthesized antenna systems are evaluated in terms of antenna radiation patterns and the corresponding channel capacities. The results reveal the superiority of synthesized antenna systems compared to conventional omnidirectional antenna systems in the considered urban street scenario. Moreover, the findings from the antenna synthesis based on dynamically measured MIMO radio channels confirm the results from the raytracing channel simulation based antenna synthesis.

“…It is shown that due to existence of dominant angles of arrival (AOA) different radiation patterns are advantageous for urban and rural scenarios. In [8] a procedure of antenna synthesis using ray-tracing simulations for multiple antenna systems is presented. Based on this procedure nearoptimum vehicular MIMO radiation patterns can be developed.…”

This paper presents the design and evaluation of a compact antenna system with pattern reconfigurability at 2.6 GHz. The antenna is based on the concept of an electronically steerable parasitic array radiator (ESPAR), and its height is reduced by top loading. The antenna can generate 10 reconfigurable patterns with a maximal gain of 7.4 dBi. Furthermore, a multiple antenna system consisting of these antennas is proposed. The radiation patterns realized by this multiple-input-multipleoutput (MIMO) system are optimized for automotive urban scenarios based on the results of previous research. The S-parameter measurement results of a fabricated prototype correlate with the simulation. Furthermore, 3D measurements of radiation patterns correspond very well with simulation and gain up to 8 dBi is obtained.

An automotive concept for vehicular communications is proposed that utilizes the potential of the roof area for antennas. Antennas are distributed in cavities and on shelves in the center and on the front and rear roof ends. The arrangement of antennas on the roof allows better radiation to the front and back of automobiles than shark-fins and single cavities. Combining several modules provides space for further antennas, sensors, and integrated front-ends, as well as better spatial separation for multiple-input multiple-output (MIMO) arrays beyond 5G, and cooperative connected and automated driving. A prototype was developed and built into a car chassis. The measured data were analyzed and evaluated in the view of coverage for vulnerable road users and on correlation for the MIMO.
