Antenna Measurement In Reverberation Chamber

Nowadays,wireless communication technology is developing rapidly.which can reflect a country’s scientific and technological level from the side,demonstrating a country’s comprehensive competitiveness.In wireless communication system,communication equipment such as antenna plays a vital role.Its characteristics and quality can affect the performance of the whole system,which is very important for the accurate measurement of antenna.However,there are many difficulties and obstacles when people are searching for new antenna characterization technologies.For example,we need to consider the environment of lossy materials to measure their communication ability,so as to regulate the performance of the devices.In recent years,a new way to characterize antenna,antenna array or medium is proposed,which is to use the anechoic chamber.However,the telecommunication system is becoming more and more complex in the development,and reverberation chamber becomes an alternative method of measurement.There are many advantages of using reverberation chamber to measure antenna parameters,and the precision of measurement needs to be further studied.This thesis aims to explore the working environment of the reverberation chamber.Use reverberation chamber to reconstruct Green function in electromagnetism.We use the crosscorrelation of the scattering field generated by a single source in the reverberation chamber to recover the impulse response between the receiving antennas passively.Explored how to optimize the reconstruction quality of Green function by changing the parameters.Besides,the reverberation chamber is used to characterize the antennas and the accuracy of antenna measurement is improved effectively based on the original experiment.The tasks included experimental operations,test-bed building,devices manufacturing and selection,parameter configuration,and extraction also processing of large amounts of data using MATLAB...
