On-chip/in-package integrated antenna for millimeter-wave medium and long-range applications

A novel cost-efficient antenna solution for millimeter-wave multi-Gbps wireless communications operating over ranges above 10-20 meters in fixed Line-Of-Sight (LOS) configuration is presented. A first antenna element is integrated on-chip with a CMOS-SOI 60-GHz transceiver circuit in order to benefit from minimum interconnection losses between the front-end circuit and the antenna. This antenna is coupled to an external radiating element embedded in a standard QFN package, enabling an improved radiation gain of 4-6 dBi. Finally, a discrete-lens antenna array fabricated on standard laminate materials is placed above the packaged transceiver in order to focus the radiated beam and reach a gain in excess of 14 dBi.
