Abstract: To study matching network impact on the receiving state performance,in the state of strong coupling emitter array composed of electrically small antenna, the analysis based upon the network scattering parameters is presented according to network features of transceiver antenna,and the correlation coefficient under different termination conditions is given.Theoretical and computational results show that the matching network in the launching and receiving state has a certain commonality and meanwhile that the network termination has the obvious effect on antenna diversity performance.The theory and method for the study of strong coupling array characteristics provide convenience and conditions,and also provides strong guidance meaning in project implementation and application.
