Study on Radial Convergent Beam Angular Mirror Symmetrical Log-Periodic Strip Line SWS

A novel slow wave structure (SWS) called radial convergent beam angular mirror symmetrical log-periodic strip line SWS is presented in this paper. The structure can be considered as the azimuthal integration of two angular log-periodic strip line SWSs. The emission density of the cathode can be reduced by the adoption of radial convergence beam. The SWS can provide the gain of, …15dB at the frequency range of (35~36) GHz. The results show that the angular mirror symmetrical log-periodic strip line SWS provides a possibility for the application of larger open angle angular log-periodic SWS.
