Typical Configuration Of Antenna Measurements
Most of the ordinary antenna measurements are to measure the far-field radiation characteristics, such as the direction (amplitude, phase, polarization), sidelobe level, gain, band width and so on.
The basic step is to place a transmitting or receiving source antenna on the far field position relative to the antenna (AUT) to be measured. The antenna to be measured is erected on a rotatable platform to rotate the antenna to be measured, thereby collecting a large number of pattern samples , To achieve the antenna radiation characteristics of the measurement. As the antenna is an electromagnetic open system, the test environment will have an impact on the measurement results, it is necessary to choose a reasonable test site, as far as possible to achieve non-reflective environment, such as the construction of microwave darkroom.
