Abstract
This paper presents a 60 GHz low loss, amplitude and phase balanced radial waveguide power combiner using a structure easy to manufacture and assembly. At V band 58∼63 GHz, the return loss at each port of the radial waveguide power combiner is below −20dB, the insert loss from input port to output port is below 0.2 dB. The differences of amplitude and phase between input ports are within 0.2dB and 0.5°respectively. The simulated results show that the radial waveguide power combiner is well satisfied for high frequency and high efficiency power combining.
