CISPR25 test is used to characterize EMC performance of automotive component. To avoid miss detection of unwanted emission in this test, it is necessary to scan the measurement antenna along the wire. In this paper, we propose a no scanning method using two loop antennas placed near DUT and wire terminal. Simulation and measurement show that the proposed method picks up unwanted signal with the errors...
In this paper, a simplified specific absorption rate (SAR) measurement method using a broadband wave absorber phantom is investigated for handset antennas. The antenna factors are determined by using finite-difference time-domain (FDTD) analysis to obtain the electric-field intensity from the electric voltage of the probe in the wave absorber at 835 and 1,950 MHz. The measured electric-field intensity...
In this paper, a simplified local SAR measurement method is developed. A lightweight phantom composed of wave absorber embedded of electric field probe is designed. The relative permittivity and conductivity of wave absorber is determined in order to equalize the surface electric field of the wave absorber and the standard liquid phantom. For this purpose, it is suitable to equalize the amplitude...
