Abstract

In this study, a miniaturized microstrip Wilkinson power divider (WPD) with harmonic elimination using low pass filter is proposed. In proposed design, two large conventional quarter wavelength transmission lines are replaced with compact low pass filters. Applied low pass filters are consisted of three triangle resonators, which result in harmonics suppression and size reduction of the proposed WPD. The proposed WPD has 56% size reduction compared to the conventional one. The proposed divider correctly works at 2 GHz and suppresses second to eighth harmonics with more than 20 dB attenuation level. According to the experimental results the insertion loss of the proposed design is less than 0.1 dB n pass band. The return losses at all ports and output ports isolation parameters are better than 20 dB and 26 dB, respectively, which shows good performance of the proposed device.
