INFLUENCE OF LOCATION OF ONE AND MULTIPLE ANTENNAS ON CAPACITY OF C2C COMMUNICATION SYSTEMS

Abstract

Due to the variety of existing and future wireless services, the number of antennas installed on a vehicle is constantly increasing. However, due to design limitations or the addition of more components of electrical equipment, the number of user-friendly antenna positions is reduced. To ensure stable data connections or even higher data rates with the remaining installation space, a possible solution is to use multiple antenna systems. This document discusses and evaluates 16 possible positions of antennas for communication between cars (C2C). The radiation pattern of all antennas is determined by the antenna synthesis maximization method, which takes into account real-world limitations such as space availability, transmission power, number and location of antennas. Channel bandwidth is used to compare different settings. This bandwidth is calculated using virtual disks based on typical application scenarios. The results of this study show which antenna positions and which combinations of antenna positions are most suitable for communication between C2C. Additional time and cost constraints, as well as an increase in the range of products for the automotive industry and a large number of degrees of freedom for the multi-purpose antenna necessitate the use of advanced modeling models and design strategies. Thus, this is the starting point for this work. Here is presented and used a technique that allows you to optimize single and multiple antenna systems. The main purpose of the proposed synthesis is to optimize the radiation profiles of antennas based on constraints specific to vehicles. For antenna design, this document identifies different scenarios based on typical C2C security scenarios. The simulation is carried out in a typical worst case in urban and rural areas or on highways.
