Smallest silicon-based CBS antenna developed

Researchers from A*STAR's Institute of Microelectronics (IME) have developed the first compact high performance silicon-based cavity-backed slot (CBS) antenna that operates at 135 GHz.

About the size of a sesame seed, it is the smallest silicon-based CBS antenna reported to date for ready integration with active circuits.

IME's innovation will help realize a wireless communication system with very small form factor. It is almost two-thirds cheaper than a conventional CBS antenna.

The antenna can support wireless speed of 20 Gbps - more than 200 times faster than present day Wi-Fi.

This means there will be ultra fast point-to-point access to rich media content which is useful in online learning and entertainment.
