Abstract In the development of some type of uniform circular array DOA（direction\|of\|arrival） estimation system, a planar microstrip structure one\|eight power divider was adopted to achiever 8\|way ultradyne receivers. Based on design principle, the technology of adding matching\|line in output port was adopted in this divider, and then the circuit simulation and parameter optimization were carried out by using the commercial software Serenade. Through experimental measurement, the divider has the characteristics such as equal power distribution, good phase consistency, simple and compact structure and so on, which meets well the design requirements of this system．
