Antenna integration in millimeter-wave transceivers for high volume applications


The enormous technological progress accomplished over the last decades facilitates the utilization of millimeter-wave (mmw) frequencies for mass products like automotive radars, industrial sensors, high-speed data communication links or medical applications. The main enablers are the semiconductor technologies with constantly improving cut-off frequencies reaching several hundred GHz. The dominant limiting factor though for the mass production of low-cost mmw systems above 100 GHz is that, suitable packaging technologies are not yet finally available. The major issue for the packaging is to find a proper way to get all signals in and out of the package, since at mmw frequencies interconnects are very difficult to realize and very lossy. One way out of the dilemma is to integrate the complete transceiver together with the antenna into one single package. Compactness is the key to low losses in mmw interconnects. This also means that the antenna must be integrated into the package.
In this talk, a short overview on the packaging and antenna integration concepts for mmw transceivers is provided together with several particular approaches. The different challenges for antenna integration and interconnects can be found in [1, 2, 3, 4, 5, 6]. In the second part, complete solutions are shown where in one case the mmw frontend is integrated together with off-chip antennas in a molded 8 mm by 8 mm QFN package [7] and in another case an on-chip antenna together with a lens is mounted in an 8 mm by 8 mm QFN package as well [8]. An application example of a complete radar system with the packaged transceiver soldered on a baseband PCB with microprocessor and lens above the chip to yield a narrow beam is shown. The complete module has a size of 35 mm x 35 mm x 25 mm and allows distance measurements with a high accuracy [9]. An outlook on packages for high data rate transmission conclude the talk [10].
