Abstract: PURPOSE: A method for measuring an electromagnetic radiation pattern in a free space using a GTEM cell and a system thereof are provided to predict a total radiation power and a free space radiation pattern as to an EUT(Equipment Under Test) from a power measured at an output port of the GTEM cell using a correlation between the GTEM cell and free space. CONSTITUTION: According to the method for measuring an electromagnetic radiation pattern in a free space after modeling an EUT(Equipment Under Test)(20) as a dipole moment in a GTEM cell(10), an output power at an output port(11) of the GTEM cell is measured using 24 arrangements of coordinate axes of the GTEM cell and coordinate axes of the EUT in a specific frequency band. Then, the radiation pattern or the total radiation power in the free space as to the EUT modeled as a dipole moment are predicted using the measured total output port power.

Abstract: PURPOSE: A method for extracting radiated electric field on a ground plane using free space measurement result is provided to predict an electric field in an OATS(Open Area Test Site) using a dipole modeled using a measurement result in a FAC(Fully Anechoic Chamber). CONSTITUTION: According to the method, an electric field around an EUT(Equipment Under Test) placed in an anechoic chamber is measured. An equivalent electric and magnetic dipole is constructed using the measured electric field. A vertical and horizontal electric field radiated in an OATS(Open Area Test Site) or on a ground plane from the above dipole is calculated. Electric field distribution is calculated in the same space range as the electromagnetic field measurement as to each frequency using the calculated vertical and horizontal electric field and then a maximum value is obtained.
