Abstract
A new dual-band unequal power divider scheme is proposed with particular advantages in structural simplicity. The proposed divider employs only two stub lines without any additional lumped reactive elements and is only two cascaded sections long from the input to the output ports. The required number of transmission line sections and the stub lines is minimised by a novel combination of a stubbed dual-band power divider and single-stub, dual-band impedance matching networks through the application of the stub cancellation technique. A systematic design procedure is provided using a set of simple design formulas obtained from rigorous circuit analysis of the proposed divider.Keywords
