BGA organic module for 60 GHz LOS communications

摘要

In this paper, we present a 12×12×0.6mm3 Ball Grid Array (BGA) organic module compatible with a Tx/Rx transceiver at 60 GHz, including a linearly polarized (LP) Tx antenna and a circularly polarized (CP) Rx antenna. Both antennas cover the 57-66 GHz band with a 5 dBi gain and higher than 50% total efficiency. The Rx CP antenna has an axial ratio lower than 3 dB on the same V-band. Each packaged antenna has an overall footprint of 4.8×4.8 mm2. This BGA module is suitable for integration in WiGig certified wireless devices allowing short-range communications.
