【 摘 要 】

The microstrip angular log-periodic meander line slow wave structure (SWS) on quartz substrate with coaxial input/output coupler is studied. The effects of different structure parameters on transmission characteristics of the 25 periods SWS during Ka band are discussed in detail. The SWS with the total length of ∼6.5 mm, add coaxial input/output coupler and tapered impedance microstrip line to form an entire assembly. The testing result is accordant with that of simulation. The dispersion characteristics of the SWS were obtained to determine the work voltage. The beam-wave interaction results show that the output power is 11.4 W at the frequency of 32 GHz, with the electron efficiency of 3.3%.
