This paper presents a set of measurements and simulations to investigate the technical viability of an UHF Band open area test site (frequency range from 300 MHz to 1 GHz). The presented experimental and computational analyses show the possibility of an emission test in a reduced size open area. Modified setups of the test proposed by international standard CISPR 25 are then proposed.

By using tridimensional full-wave computer simulations three different scenarios involving antenna placement in an automobile model were analyzed. The electromagnetic impact of the vehicle model complexity was taken into account, as well as the relative position of the antenna on its roof. The simulations were run in a moderate equipped computer, and show a powerful alternative to complement and forecast real laboratory evaluations

This work presents a methodology for carrying out open site tests of VHF-FM vehicular systems. The approach here developed characterizes antennas, coaxial cables and RF amplifiers performance in terms of normalized experiments. The efficiency of the procedure adopted is also proven.
