| Summary: | Nowadays, the manufacturers apply the radiated
emission test for all of their electrical or electronic products in
order to avoid disturbance to other electrical or electronic
products and to fulfil national or international standards. An
Open Area Test Site (OATS) is one of the facilities used in the
radiated emission measurement which requires the equipment
under test (EUT), a receiving antenna with the antenna mast, the
ground plane, and the radiated emission measurement device.
The focus of this research is mainly about the ground plane of the
OATS which can reflect the emission from the EUT to the
receiving antenna. The perfect ground plane is very expensive;
therefore the wire mesh ground plane can be used to cut the cost.
The investigation of the ground plane could lead to an applicable
radiated emission test and the accuracy of the measurement by
using the mesh ground plane in OATS. In solving the problems
related to the ground plane, the measurement of Normalized Site
Attenuation (NSA) will be compared with the theoretical NSA.
NSA is measured by transmitting signal from the frequency of 30
Mega Hertz (MHz) until 1000 MHz, assuming only two waves
propagation which are direct wave and reflected wave. |
