The theory of wilkinson power combiner and ratrace coupler is analyzed by using the odd - even mode method in this thesis. on the basis of the theoretical analysis, we designed and tested the wilkinson power divider, the modified wilkinson power divider and ratrace coupler, good agreement is observed. in addition we propose a power combiner based on a waveguide - to - microstrip transition using antipodal finlines. this structure united the two functions of transition and equal power division, it can not only be used in the circuit power combiner but also be used in spatial power combiner
另外提出一種基於鰭線波導微帶過渡功分器，該結構將過渡與功分兩種功
能完全結合，不但可以用於電路合成式功率合成，也可用於空間功率合成中。對功率合成器，其主要指標是輸出功率和效率，其中提高輸出功率和效率的一個方法是在輸出端抑制諧波，主要是對二次諧波的抑制。
