Highly efficient large-domain moment-method analysis and CAD of radio-frequency antennas mounted on or situated in vehicles

Highly efficient large-domain moment-method analysis and CAD of radio-frequency antennas mounted on or situated in vehicles are presented. A Golf GL is analyzed, with different wire antennas mounted on or situated in it, at 98 MHz (FM) and 860 MHz (cellular telephone band). For different antennas, parts of the vehicle that are of the most importance for the antenna-vehicle electromagnetic coupling are identified influence of the positioning and orientation of the antennas on the antenna reflection coefficient is studied. It is demonstrated that an accurate and efficient numerically rigorous electromagnetic computational method must be considered as an indispensable tool for the analysis and design of vehicular wireless communication systems.
