Summary:
Usually, the antenna and electromagnetic performances can be simulated by various commercial available software (HFSS, CST, GEMS, FDTD.,etc.). Unfortunately, the implementation of hardware for these devices may have error during manufacturing. Electrical performance testing is required even for pilot run or mass production of these devices. Usually, the passive electrical performances, such as impedance, VSWR, return loss, power gain, power patterns, axial ratio, antenna overall efficiency, can be measured by the vector network analyzer inside anechoic chamber. Except for the passive electrical performances, the active electrical performances, TRP (total radiation power) and TIS (total isotropic sensitivity) are required for wireless communication system. The uncertainty of passive and active measurements not only depends on the experience of operator but also the signal to noise ratio. In this paper, overview the activities of passive and active measurement at CRC (Communication Research Center) of OIT (Oriental Institute of Technology) are presented at this paper. Various kinds of antenna measurement systems and TRP and TIS communication measurement system are presented.
