This paper presents a compact six-port power divider with simple structure that performs two independent out-of-phase divisions. The proposed power divider consists of a uniplanar ring crossover with four transmission lines for output and two feeding lines. The $S$ -parameter matrix of the proposed power divider is derived analytically, and it is shown that the two independent out-of-phase divisions are realized when the circumferential length of the ring is one guided wavelength $\lambda _{g}$ whereas conventional power dividers require a $2\lambda _{g}$ or $2.5\lambda _{g}$ ring. Two power dividers configured with striplines were designed to have −10-dB impedance bandwidths of 5% and 10% with a center frequency of 2.45GHz. The designed power dividers were fabricated and two independent out-of-phase divisions having small amplitude imbalance were verified by measurements. Because of its compactness, the proposed power divider might be applied to the feeding network of dual-feed dual-polarized array antennas with narrow element spacing.
