Planar ultra wideband inphase power divider

A planar inphase power divider, which has ultra wideband performance, is presented. Die proposed device utilizes a T-microstrip junction combined with an electromagnetic coupling between a slotted ground plane and an elliptical patch at the centre of the T-junction. A resistor is also used to enhance the isolation between the output ports of the power divider. The simulated and measured return losses at the three ports of the device, isolation between its output ports, and phase stability of the output signals prove the ultra wideband performance of the presented device.
