摘要: A compact microstrip dual‐band in‐phase filtering power divider is presented in this study. The integrated two stub‐loaded resonators are applied to realise the dual‐band filtering response and compact size. Based on the even–odd‐mode analysis, an analytical model of the proposed power divider structure is presented. To improve the frequency selectivity, a source‐load cross coupling is introduced by placing input and output coupling lines closely. A prototype of the dual‐band in‐phase filtering power divider centred at 3.5 and 5 GHz with …
