This paper presents the design and simulation of a semi-lumped low-pass filter with finite-frequency attenuation poles at 10 GHz for integration into a 35 GHz harmonic harvesting rectifier in wireless power transmission (WPT) systems. Implemented on an RT6002 substrate, the filter enhances RF-to-DC conversion by suppressing unwanted harmonics, ensuring stability and efficiency. The design, optimized for compactness and high selectivity, is validated through ADS and CST simulations, confirming sharp roll-off and strong stopband attenuation. This work contributes to renewable energy harvesting by improving rectenna-based WPT systems for self-powered IoT and sustainable energy applications.
