A compact high‐isolation planar eight‐way power divider using a zero‐phase isolation circuit is presented. The composite right‐ and left‐handed transmission line is applied to achieve good input impedance matching, and the hybrid coplanar waveguide (CPW)/microstrip line is used to get a compact circuit size in the eight‐way power‐dividing circuit. In addition, the zero‐phase microstrip line is applied to obtain high output isolation. The design has been verified by measurements, which show good agreement with simulations. The fabricated eight‐way power divider measured results show that the central frequency of 2.2 GHz, 15 dB input return loss bandwidth of 36.4%, 0.2 dB insertion loss bandwidth of 29% and 20 dB output isolation bandwidth of 27% are achieved.
