Antennas have often capped the potential speed of a wireless link - the 450Mbps in modern 802.11n WiFi routers is directly linked to the use of a MIMO antenna array to catch signals more effectively, for example. That ceiling is about to get much higher, if A*STAR has anything to say about it. The use of a polymer filling for the gaps instead of air lets the Singapore agency create a 3D, cavity-backed silicon antenna that measures just 0.06 by 0.04 inches, roughly the size of a seed on your hamburger bun, even as it increases the breakneck pace.
