Design of an ultra‐wideband power divider with harmonics suppression

The design of an ultrawideband (UWB) power divider with harmonics suppression is presented. With the proposed approach, the size of the quarter-wavelength transmission line can be reduced and the high order harmonics can be suppressed. The design equations are deduced by transmission line theory. A prototype power divider operated at UWB band is designed and fabricated. Experimental results show good performance of the proposed design. In addition, a stop-band with rejection level more than 20 dB is from 17.3 to 24.5 GHz. © 2014 Wiley Periodicals, Inc.
