Antennas have advanced almost as fast as the silicon in the devices they serve, over the 30-year history of MWC, both inspiring and exploiting innovations in materials design and miniaturization. Like the chips, their trajectory seems to have followed a Moore’s Law of their own, driven down in size not just by technical advances but by the climb up the frequency ladder. As wavelengths shortened, so did the optimal antenna size. This reduction in size, coupled with the advent of beamforming, has shaped antenna design increasingly, giving rise to new geometries for optimal signal transmission. These trends have also ushered in antenna arrays acting in concert to optimize transmission and boost signal gain, in turn affecting design of the individual…
