2007 IEEE transactions on microwave theory and techniques  
The integration of an on-chip folded dipole antenna with a monolithic 24-GHz receiver manufactured in a 0.8-m SiGe HBT process is presented. A high-resistivity silicon substrate (1000 cm) is used for the implemented circuit to improve the efficiency of the integrated antenna. Crosstalk between the antenna and spiral inductors is analyzed and isolation techniques are described. The receiver, including the receive and an optional transmit antenna, requires a chip area of 4.5 mm 2 and provides
