Domestic scholars are often concerned with the characteristics of the plasma cylindrical antenna and the plasma reflector antenna. However, foreign scholars have begun to study the plasma array antenna and used it to design smart antenna. In order to understand this new design idea, based on the plasma electromagnetic scattering theory, a theoretical and experimental study on the directive circular antenna array with a center element driving is presented. A sixteen-element plasma passive oscillator circular array, the mechanism of whose single-beam and multi-beam is transmitting, is established. And an experimental system is established to test the radiation result of circular antenna array. The measured results of radiation patterns are in good agreement with the computational values, verifying that electromagnetic waves can be directional and multi-beam transmitted in this circular antenna array. The advantages of this antenna array are fast switching of the radiation parameters, rapid reconstruction, radar stealth and so on.
