Abstract:

Based on universal antenna measurement system,a new approach is proposed for the frequency extending design and engineering applications.The coherence of local oscillation of mixers and the consistency of up-down frequency converter channels are discussed.The frequency extending is applied to the existing planar near field and far field antenna measurement systems below Ka band.Finally,the antenna measurement results of an array with 8 antenna units of EHF frequency band under two different test systems are presented.The results show that there is a good agreement between the millimeter antenna measurement system and frequency extending system,which demonstrates that the design of frequency converter system can meet the requirement of millimeter wave antenna measurement and has good measurement accuracy.The design for the simplified frequency converter system is generic and low in cost and thus applicable to millimeter antenna measurement.

Key words: antenna measurement;planar near field;far field;millimeter wave measurement;frequency extending
