Abstract

Abstract: The even-odd mode theory, wave superposition and impedance matching are used to design the 3-dB power splitter, then the structure and the parameters of the power splitter are simulated by HFSS cord. Finally the optimistic results are acquired: reflection loss in input port 1 is -41.42dB; isolation between the port1 and 4 is -44.86dB; power splitting in output port 2, 3 are -3.02 dB, -3.01 dB；input VSWR is 1.017.

Key words: 3-dB power splitter, LHCD, HFSS simulation and optimization
