The design of a wideband in‐phase power divider/combiner is presented. It uses a three‐line coupled structure with slotted ground and 100 Ω isolation resistor for an increased band using easy‐to‐manufacture dimensions. The operation of the device and its design procedure re explained for an enhanced isolation, almost ideal phase performance, and a balanced power division between its two output ports. The simulated and experimental results of the developed 1.5 × 1.5 cm 2 power divider show 90% fractional bandwidth assuming 10 dB return loss as a reference with less than ±1° phase imbalance between the output ports. © 2014 Wiley Periodicals, Inc.
