In this paper, we present a 122-GHz low-cost, robust, and small form-factor frequency modulated continuous wave (FMCW) radar sensor in package. The sensor is based on 130 nm SiGe BiCMOS transceiver chip which is integrated in an embedded wafer level ball grid array (eWLB) package. The chip features a fully-differential, frequency-multiplier based bistatic radar with IQ receiver and IQ modulation in the transmitter. The highlight of the sensor includes a transmit and a receive antenna array designed in the redistribution layer of the eWLB package. Each antenna array comprise 43 rhombic elements providing a measured gain of around 15.5 dBi. The radar system-in-package demonstrates a measured effective isotropic radiated power of 21.5 dBm at 122 GHz which is the highest EIRP up to date for a D-band radar sensor not using an external lens. The radar sensor was also functionally tested in an FMCW configuration after mounting on an FPGA baseband board.
