This paper presents a process of designing compact TE01-TE02 mode converters with broadband. Mode conversion condition are approximately derived while propagation constants vary along axis and initial structure of the mode converters is calculated. The initial structure is optimized utilizing iterative method. Two period TE01-TE02 mode converter in Ka band and one period mode converter in W band are designed, and the bandwidths (above 95% conversion efficiency) reach 2.47 GHz and 8 GHz respectively. CST simulation data agree well with those calculated by coupled mode algorithm for both converters.
