Abstract

A 6-way power divider with the combination of Bagley polygon power divider, Wilkinson power divider and defected ground structure are proposed in this specific work. A 100 ohm isolation resistor is used to achieve good isolation in Wilkinson power divider. The proposed configuration having, 2-section of 3-way triangular shape Bagley polygon power divider connected with the output of 2-way Wilkinson power divider. Parameters of the proposed configuration are calculated at the centre frequency of 1.5 GHz. For verification the proposed design is fabricated with the dielectric constant of 4.4 and loss tangent of 0.02. The result is having triple frequency response at 1GHz, 1.5GHz and 2GHz frequency with a gap of 0.5GHz. Return loss at all the ports below -10 dB, transmission coefficient above -7.5 dB and isolation among output ports are better than -10 dB is achieved. Measured results by spectrum analyzer are compared with simulated results by computer simulation technology microwave studio and found satisfactory.
