PROJECT TITLE :

Dual-band in-phase filtering power dividers integrated with stub-loaded resonators

ABSTRACT:

A compact microstrip dual-band in-part filtering power divider is presented during this study. The integrated 2 stub-loaded resonators are applied to understand the twin-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 enhance the frequency selectivity, a supply-load cross coupling is introduced by putting input and output coupling lines closely. A prototype of the dual-band in-phase filtering power divider centred at three.5 and 5 GHz with three dB fractional bandwidth of 7.four and four.twop.c is meant, fabricated and measured. The size of the fabricated power divider is zero.twenty sevenλg × 0.35 λg. The simulated and measured results are presented and show smart agreement.
