Abstract

A dual band power divider for mobile TV services working at two arbitrary frequencies of 670MHz, respectively 1465MHz is designed. The transmission lines used are Dual-Composite Right Left Handed (D-CRLH) ones designed to act as inverters at two frequencies with similar performances and a minimum of unit cells. They are implemented using microstrip technology and lumped elements. The power divider exhibits a very large relative bandwidth for the coupling loss at both frequencies (around 90%) and an isolation of 27dB for the first frequency, respectively 35dB for the second one.
