162-Discussion on the Electrical Characteristics of Tera-Hz in Organic Substrate

Communication technologies have been on a relentless path of evolution, driven by the ever-growing need for faster, more reliable, and more efficient data transmission. From the early days of radio communication to the modern era of <tex xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">$5\mathrm{G}$</tex> networks, each new generation of technology has expanded the boundaries of what is possible, enabling new applications and transforming industries. As we stand on the cusp of another significant leap forward, the exploration of higher frequency bands, particularly those in the terahertz (THz) spectrum, is gaining momentum as the next frontier in communication technology. The transmission speed could be dozens of times higher than previous generation while the communication generation evolves to <tex xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">$6\mathrm{G}$</tex>. Therefore, in order to meet larger bandwidth and limitations of frequency license, the communication frequency may reach up to sub-THz which's range is 100GHz-300GHz. At such high frequencies, signal losses from the IC to the antenna feed point will increase. Discussion of the corresponding transmission architecture, loss characteristics, and feasibility evaluation of application in packaging are ongoing.
