Radiation Effects of On-Chip Transmission Lines on Devices Lying in a Same Chip

In the wake of technological progression, there has been a marked reduction in chip dimensions. Concurrently, a consequence of this miniaturization is the generation of electromagnetic radiation from microstrip lines within the chips during their operational phases, potentially jeopardizing the functionality of nearby electronic components. While the radiation effects of microstrip lines are inconsequential at lower frequencies, this paradigm shifts dramatically as frequencies reach the gigahertz (GHz) domain. At these elevated frequencies, the electromagnetic wavelength becomes comparable to the microstrip line's length, compelling the adoption of meticulous simulation analyses to discern the electromagnetic influence on neighboring equipment. To address this, the current study embarks on an exploration of radiation analysis predicated on a microstrip line model at a frequency of 50 GHz. Utilizing the power transiting through a virtual plane, we probe the interference exerted by the microstrip line on adjacent devices. This endeavor serves to furnish a frame of reference for the high-frequency electromagnetic perturbations impacting nearby electronics.
