This paper describes the modeling, design and performance of 30 GHz low noise amplifiers (LNAs) integrated with slot antennas on GaAs monolithic microwave integrated circuits (MMICs). Various designs are compared, showing the tradeoffs between achievable noise figure, gain and overall chip size.
A miniature on-chip antenna/inductor is presented which can radiate effectively while providing the required L and Q for the resonant tank of a VCO. Antenna gain and radiation pattern measurements demonstrate a maximum gain of -22 dBi at 45deg off boresight. With 0 dBm of radiated power, the on-chip antenna supports a 2 m communication link with an off-chip patch antenna connected to a low noise receiver...
The conditions are investigated under which standard digital bulk Si technology can yield efficient on-chip antennas and baluns for fully differential transmitter and receiver implementations. The effects of the IC material properties and the antenna geometry on radiation and impedance characteristics have been studied. 24 GHz on-chip antennas on lossy Si have been successfully demonstrated, using...
A novel system-in-package (SiP) implementation is presented for a transmitter (TX) module which makes use of electromagnetic coupling between the TX chip and package antennas at 5.2 GHz. The TX chip is realized in 0.13 mum CMOS process and comprises an on-chip antenna. This on-chip antenna serves as the oscillatorpsilas inductor as well. The TX chip is housed in a low temperature co-fired ceramic...
