In this paper, a new kind of wideband, low-loss composite right/left-handed (CRLH) transmission line (TL) and a Wilkinson power divider are presented. The TL is composed of a parallel meander inductor and a series cutting capacitor based on coplanar waveguide (CPW) structure. The power divider is designed by substituting the CRLH-TL into the conventional transmission line. The experiment results show that the TL has a good agreement with the desired results, exhibiting the return losses under 12 dB from 8.4 GHz to 34.4 GHz. The operating frequencies of the power divider are 12.05 GHz to 13.15 GHz and 16.50 GHz to 19.30 GHz, respectively. The 20 dB bandwidths are 8.9 % and 17.9 %, respectively. Typical experimental measurements are conducted and compared with the simulated results.
