Ranging From Sub-microstrip Power Divider Design And Simulation

Divider is the important RF device in a wireless communication system . therefore,microstrip divider has small size, and is easily integrated, so it is widely used in radio frequency microwave integrated circuits. In the RF circuit, there often will be the demand of the uneven distribution of the RF power ,so the uneven microstrip power divider is of important value in the actual RF circuit. Comparing with the equal divider, the design of the neven microstrip power divider is more complex, there will be consider more factors.In this paper, one divides into two uneven microstrip power divider was studied, the principle of Wilkinson microstrip power divider was analysed, and select the centre frequency of 2.45 GHz, the relative dielectric constant microwave dielectric of 4.3, designed a distribution A ratio of 1:2 at the Wilkinson microstrip power divider. then use a programming language VB to designe Microstrip Wilkinson divider computing software, achieving computer-aided design of the Microstrip Wilkinson power divider. We can enter the parameters needed to calculate the structure and size by using the software. Upon completion of microstrip power divider designed on the basis of this paper, Agilent's electromagnetic simulation software ADS (Advanced Design System) designed by Wilkinson on microstrip power divider for the electromagnetic simulation, and optimization through multiple edits, received a best microstrip power divider structure. Finally the simulation results show that, the paper designed by Wilkinson microstrip power divider communications systems tomeet the actual demand.
