A Novel Dual Band Impedance Matching Network and Analysis of Matching Bandwidth

In this paper, a novel dual band (DB) impedance matching network (IMN) with two transmission zeros (TZs) out-of-band is proposed. Two-section shunt transmission lines (TLs) is proposed to compensate susceptance of source admittance at dual operating frequencies. Another serial TL aims to modulate source conduction to target conduction
$G_{0}$
. Two TZs of arbitrary frequencies is imported by the two-stage TLs. Furthermore, the matching bandwidth (BW) of the proposed DB IMN has been analyzed.
