ABSTRACT In this study, a miniaturized Wilkinson Power Divider (WPD) has been designed. Central frequency of the passband for designed power divider (PD) is 1.55 GHz. Using the oval and rectangular- shaped resonators instead of each quarter-wavelength transmission lines of conventional Wilkinson power divider (CWPD) will result in reducing the size of proposed PD by 55%. Presented PD has many advantages, such as low insertion loss (3.015 dB), high return loss (24 dB), high isolation rate between output ports (27 dB), and suppressing the high-frequency harmonics (eliminating the 2nd to 12th unwanted harmonics). Finally presented PD was fabricated and measured on The RT-5880 with ϵr = 2.2 and TanD = 0.0009 with a thickness of 0.787 mm as the substrate. The measured results have good agreement with the simulation one. Due to the appropriate specifications and the small size of the designed divider, this divider can be nominated to use in many communication applications.

具有 12 次谐波抑制功能的小型化威尔金森功率分配器

摘要 在这项研究中，设计了一个小型化的威尔金森功率分配器 (WPD)。设计的功率分配器 (PD) 的通带中心频率为 1.55 GHz。使用椭圆形和矩形谐振器代替传统威尔金森功率分配器 (CWPD) 的每个四分之一波长传输线将导致建议的 PD 尺寸减小 55%。PD具有低插入损耗（3.015dB）、高回波损耗（24dB）、输出端口间隔离率高（27dB）、抑制高频谐波（消除2～12次无用谐波）等诸多优点）。最后呈现的 PD 是在 RT-5880 上制造和测量的，ϵr = 2.2 和 TanD = 0.0009，厚度为 0.787 mm 作为基板。实测结果与仿真结果吻合较好。
