In this work, 3D printed interposer layer is proposed to enable vertical stacking of different heterogeneous components and substrates. Different design parameters were first simulated using HFSS to optimize for maximum possible bandwidth. After optimization, the design parameters were used to fabricate a wireless battery less digital modulator as an example IoT device. Measurement results are provided to validate the design and simulation results. � 2019 IEEE.en-US3D printingEnergy harvestingInterposerPassiveWirelessEnergy harvestingInternet of thingsNetwork componentsRadio3-D printingDesign and simulationDigital modulatorsHeterogeneous componentHigh-density packagingInterposerPassiveVertical stacking3D printersConference Paper168716922019-May8811138PECCA
