Cost-effective 60-GHz Modules with A Post-wall Planar Antenna for Gigabit Home-link Systems

Cost-effective 60 GHz modules were developed for home-link systems which needed the bit rate of several Gbps. The modules are composed of a packaged MMIC mounted on the printed circuit board and a post-wall planar antenna formed on the backside of the board. The antenna gain is 20 dBi. The board with the size of 75 × 32 × 1.2 mm3 is inserted into the card-edge connector to feed the IF signal and the DC power. The module can be characterized to have no mm-wave terminals. When the output power of the transmitter module ( Tx ) was 8 dBm at 61.0 GHz, the IF output power of the receiver module ( Rx ) PIFout was -37 dBm at the distance D = 10 m between Tx and Rx. This experiment suggests the capability of the transmission with the bandwidth of 2.5 GHz and the C/N of 25 dB in the home-link systems.
