Off-chip antenna designs for fully integrated, low-cost millimeter-wave transceivers

This paper presents two specific antennas that can be integrated into a chip package. Both are optimized to be connectable to a single chip radar transceiver. Thus a fully integrated, surface-mountable and low-cost radar sensor results. The first antenna design is a double dipole antenna for a frequency range from 108 GHz to 129 GHz that can be connected to the MMIC using flip chip technology. The second antenna is a four element patch array with a series-parallel feed network and a bandwidth from 143 GHz to 154 GHz. It can be placed beside a MMIC and connected to it using wire bond technology. Details of both antennas are shortly explained. Afterwards measurement results are given.
