在确定天线数值模型的基础上，结合高功率微波天线的真空需要与实验装置情况，设计并加工了X波段基于漏波波导的高功率微波天线，对该天线分别进行低功率和高功率条件下的性能指标测试。在低功率条件下天线测试结果表明：在9.6 GHz下天线增益为26.3 dBi，天线方向图与数值模拟结果一致。在SINUS881加速器上利用返波管进行了天线高功率测试，实验结果表明：天线功率容量大于200 MW，高功率测试方向图、低功率测试方向图和数值模拟取得较为一致的结果。

On the basis of the antenna numerical structure, an X-band high power microwave (HPM) antenna based on leaky waveguide was fabricated and tested for the radiation performance and power handling capacity for HPM applications. The experimental results in low power test indicate that, the antenna gain is 26.3 dBi at 9.6 GHz and the agreement of radiation pattern is obtained between measured values and simulation results. The experimental results of radiation pattern of the antenna with X-band BWO driven by SINUS881 indicate that, the power handling capacity is above 200 MW besides reasonable agreement is obtained between measured values and simulation results. The feasibility of the antenna in HPM application is validated.
