摘要
针对高损耗介质材料电磁参数的宽频带测试问题,提出了利用脊波导进行测试的新方法,建立了电磁参数测试系统,并采用TRL技术进行了系统校准。该方法仅用3个波段的脊波导即可覆盖2.0～18.0GHz宽频带范围内的电磁参数测试,具有频带宽、体积小、测试精确度高等优点。
By using double-ridge wavegnide, a test method has been proposed for broadband measurement of electromagnetic properties of high-loss dielectric materials. The test system for the measurement of electromagnetic properties is built and calibrated by TRL calibration method. By using three wavebands of double-ridge wavegnides, the frequency band can cover 2.0-18.0 GHz. The method features broad frequency band, small volume and high accuracy.
