A fully-integrated 60-GHz transceiver system with on-board antenna assembly is presented. Incorporating on-off keying (OOK) and low-cost antenna designs, this prototype demonstrates a low-power solution for multi-Gb/s wireless communication. The enhanced OOK modulator/demodulator obviates baseband and interface circuitry, revealing a compact solution. Two antenna structures, folded dipole and patch array, are employed to fully examine the performance. Designed and fabricated in 90-nm CMOS technology, the transmitter and the receiver consume 183 and 103 mW and occupy 0.43 and 0.68 mm2, respectively. With 4 Ã 3 patch antenna array, the transceiver achieves error-free operation (BER < 10-12 ) for 231 -1 PRBS of 1 Gb/s over a distance of 60 cm.
