A wide‐stopband Wilkinson power divider (WPD) is proposed, which can be realised by using open dual‐transmission line (TL) stub and L‐type artificial lowpass TL structures. To further achieve miniaturisation, synthetic TLs are also employed. The simulated and measured results are consistent, and the measured | S 21 | and | S 31 | (insertion losses) have shown stop‐bandwidth of larger than 18.33 GHz (1.67–20 GHz) and 18.28 GHz (1.72–20 GHz), respectively, under the condition of 30 dB harmonic suppression level. The wide‐stopband of the WPD can cover 2 f o –22.2 f o ( f o = 0.9 GHz), and the occupied area of the WPD (not include the feeding network) is only 0.11 λ g × 0.06 λ g ( λ g : guided wavelength at f o ).
