The analysis and design of three-port microstrip power-divider

摘要

In this paper, a wideband three-port microstrip power-divider 1 is discussed with the central frequency of 2.45GHz. The electromagnetic simulation software HFSS is used to analyze the side-fed and probe-fed equal power-divider and the 2:1 unequal power-divider in the L and S-bands. The simulation results show that the minimum of the imports' VSWR can reach 1.04 and the performance of S-parameter is preferable. This power-divider can be used to compose the feed network of antenna array.
