【Abstract】 It analyzed and studied for various configurations of rotationally symmetric monopole antenna by applying extended moment method, Two kinds of rotationally symmetric monopole antenna with broad band characteristics and center frequency of 750MHz are designed and fabricated. These kinds of broad band antenna for impulse radar have the characteristics of high gain、omnidirectional and ultra broadband.All of them are analyzed by extended moment method. Theoretical caculation and partial experimental results are compared and reasonably agreement are obtained,The research provides theoretical basis for practical design.更多还原
