A 24-GHz Fully-integrated CMOS Transmitter with On-chip Antenna

The ever-increasing demand for low-cost portable devices has motivated the research on high frequency CMOS communication integrated circuits. We designed and implemented a transmitter chain that will be part of a single-chip 24-GHz CMOS radio for sensor network applications. The radio includes a RF transceiver, an on-chip antenna, a baseband processor, a sensor, and eventually a battery. The integration of an antenna on the same chip greatly simplifies the package, lowers the device cost to less than $1, and makes the radio easy to use.
