The design of a planar in‐phase power divider for wideband applications is presented. The proposed divider uses a broadside coupled microstrip/slotline configuration with an improved isolation between the output ports using suitable isolation resistor. The proposed design is suitable for single layer integration as both the input and output ports are located at the same layer. Although the device can be used for any wideband application, the developed prototype is designed to operate within the band 2–5 GHz, which is used in microwave‐based head imaging systems. The simulated and experimental results of the developed divider show equal power division with less than 0.5 dB of additional insertion loss, less than 2° of phase imbalance, more than 13 dB of isolation and more than 10 dB of return loss over the band 2.3–4.7 GHz. It has a compact size with an overall dimension of 30 × 30 mm 2 . © 2015 Wiley Periodicals, Inc. Microwave Opt Technol Lett 57:789–791, 2015
