摘要：

In this paper, a miniaturized dual-band power divider based on artificial transmission lines is proposed for GSM applications. The design consists of four sections of recently developed planar artificial transmission lines, an LC tank circuit in shunt, and an isolation resistor. The experimental results show that the proposed configuration has good performance at both 0.9 GHz and 1.8 GHz. Meanwhile, it achieves a significant size reduction compared to traditional dual-band planar power dividers. At the center frequency 1.35 GHz, the dimension of the proposed dual-band power divider is only 43 mm x 21 mm, or equivalently 0.29 lambda g x 0.14 lambda g. With the harmonic suppression nature of artificial transmission lines and the shunt LC tank, the wideband response of the proposed dual-band power divider reveals good harmonics suppression.
