Abstract

A new approach to design of a dual-band power divider with only one section transmission line is proposed. Apart from the isolation resistor, admittance matrix is used to synthesize the dual-band divider. According to the required admittance matrixes at two frequencies, a modified configuration with shunting open/short stubs at each port is presented. A new compact dual-band (operating at 1.0 GHz and 4.5 GHz) is developed to validate this proposal. Experimental results demonstrate that the return loss is better than -19.2 dB, insertion loss less than 0.59 dB, and isolation better than 23.61 dB at two operation frequencies. The measured relative bandwidths of 15 dB return loss are 35.9% and 12.4% for the lower and higher bands, respectively.
