【Abstract】 This paper present an ultra-wide-band 180°power divider based on transition between microstrip and slot-line to achieve ultra-wideband 3dB power distribution.In order to expand the bandwidth of the power divider,the fan-shaped transition structure is used in this workin instead of the traditional round transition structure.The simulation results and the measurement results are agreed well.The insertion loss of less than 1.5dB at the frequency range of 3.1~10.6GHz has been obtained.The amplitude balance is less than 0.8dB and the phase balance is less than 1°between the two output ports;the reflection coefficient at the input port is less than-12dB.更多还原
