摘要

In this paper we designed a microwave material measurement system by using slotted line waveguide.Compared with the VNA,this system have the smaller size and lower cost.Considering the test technical specifications, test methods of complex permittivity of microwave materials, and the performance of test system,we used the short-circuited line method to test the complex permittivity of the microwave material, and used the TI DSP [1] (TMS320C6747) as a minimum core processor system. Developed a set of X-band automatic slotted line system, this paper carried out the design of the prototype test system and the programing of the system's automated testing software. Finally,we used the measuring system to test two kinds of sample(fiberglass and quartz) and compare the result with the other result testing by the VNA.it is not difficult to conclude the measured result is relatively accurate.
