An exact design for seven‐way Bagley power divider (7‐way BPD) is introduced. The objective of this article is to derive general closed‐form expressions for the impedances between adjacent ports for unequal‐split 7‐way BPD. The values of the impedances control the output power ratio. Full derivation of S ‐parameters followed by exact impedance equations will be presented. A parametric study in addition to several examples will be given to validate the proposed derivation including: 7‐way BPD with output power splitting ratios of: 1:6:15:20:15:6:1, 1:2:3:4:3:2:1, and 1:3:1:3:1:3:1 operating at 1 GHz. An experimental value for the reflection coefficient ( S 11 ), at the design frequency is found to be −40.1 dB. A very good agreement between theoretical, simulated, and experimental results is achieved which proves the correctness of the presented approach. Therefore, it can be used to design 7‐way BPDs for any output power ratio.
