A compact upper wideband unequal power divider with planar configuration is proposed. This power divider includes two-section asymmetric coupled transmission lines and non-uniform microstrip. The measured results of the prototype divider show that the 12.1 dB return loss and ports-isolation band is in the range from 3.1 to 10.6 GHz, the unequal power division coefficient is almost in the range 4.03–5 dB (the simulated result: 4.3–4.75 dB).
