Abstract

Abstract A Wilkinson power divider (PD), which can suppress the second, third, and fourth harmonics is proposed. The PD is implemented based on an asymmetric meta-structure. The meta-structure is constructed be combing defect ground structure (DGS) and spoof surface plasmon polariton (SSPP). It can not only realize the impedance conversion function in the operating frequency band, but also realize the suppression of the second, third, and fourth harmonics. The simulation and measurement results show that this structure can achieve −32 dB suppression for the second harmonic, −31 dB suppression for the third harmonic, and −28 dB suppression for the fourth harmonic respectively.

多谐波抑制威尔金森功率分压器的设计

摘要提出了一种能够抑制二次谐波、三次谐波和四次谐波的威尔金森功率分配器。PD是基于非对称元结构来实现的。该元结构由缺陷接地结构（DGS）和欺骗表面等离子体激元（SSPP）构成。它不仅可以实现工作频带内的阻抗转换功能，还可以实现对二次谐波、三次谐波和四次谐波的抑制。仿真和测量结果表明，该结构可以实现−32 二次谐波的dB抑制，−31 三次谐波的dB抑制，以及−28 dB对四次谐波的抑制。

期刊介绍： Frequenz is one of the leading scientific and technological journals covering all aspects of RF-, Microwave-, and THz-Engineering. It is a peer-reviewed, bi-monthly published journal. Frequenz was first published in 1947 with a circulation of 7000 copies, focusing on telecommunications. Today, the major objective of Frequenz is to highlight current research activities and development efforts in RF-, Microwave-, and THz-Engineering throughout a wide frequency spectrum ranging from radio via microwave up to THz frequencies. RF-, Microwave-, and THz-Engineering is a very active area of Research & Development as well as of Applications in a wide variety of fields. It has been the key to enabling technologies responsible for phenomenal growth of satellite broadcasting, wireless communications, satellite and terrestrial mobile communications and navigation, high-speed THz communication systems. It will open up new technologies in communications, radar, remote sensing and imaging, in identification and localization as well as in sensors, e.g. for wireless industrial process and environmental monitoring as well as for biomedical sensing.
