Design of the Wilkinson power divider with multi harmonic suppression
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.
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.
