In this article, an ultra wideband power divider is proposed, analysed and designed. The design approach of the proposed power divider is derived from even/odd mode analysis. The design approach is validated, and the power divider is simulated by two full-wave electromagnetic simulators (ADS and Sonnet) and fabricated on a substrate with a thickness of 0.635mm and relative constant of 10.2. Measured results of the proposed power divider show equal power split, excellent insertion loss and good return loss at all the three ports, and a good isolation between the two output ports is achieved over the specified 3.1-10.6GHz ultra wideband range. In the input port return loss, there are two transmission poles around 5.2 and 9.5 GHz. The overall size of the proposed power divider is just 5.8 x 4.3mm(2).
