چکیده :

This paper focuses on designing a sharp roll-off band-pass equal power divider based on the concept of the substrate integrated plasmonic waveguide (SIPW). It is composed of a SIPW at the input that splits into two half-mode SIPWs (HSIPW) at the outputs. Both SIPW and HSIPW consist of slots etched on the top metallic layer of substrate integrated waveguide (SIW) and the half-mode SIW, respectively, to support the spoof surface plasmon polariton (SSPP). Low and high cut-off frequencies can be independently tuned by the parameters of the SIW and SSPP sections, respectively. A prototype of the proposed power divider was fabricated and tested to verify the presented design. The simulated and the measured results show that the electromagnetic waves are split equally between output ports within the passband and are prohibited from propagating in the out-of-band rejection with sharp attenuation.
