Abstract :
To carry out measurements in frequency domain (FD) indoors the expensive anechoic chambers are necessary. Time domain (TD) method allows to eliminate the reflections from adjacent objects. Therefore it is possible to carry out TD measurements indoors without anechoic chamber. The TD method lets to use considerably cheap signal generator and receiver than those used in FD. The additional advantage of outdoor TD measurement systems is interference immunity. The report contains indoor and outdoor TD antenna measurement systems utilizing Geozondas Ltd equipment description. The errors are analyzing. It is possible to use the same signal receiver, i.e. sampling oscilloscope, both in frequency and time domain measurements. The TD antenna measurements are possible to carry out in far and near fields
