Design and Validation of a Printed Circuit Board Integrating a BGT60LTR11AIP mmWave CW Doppler Radar Sensor

In recent years, millimeter-wave (mmWave) radar technology has seen rapid adoption beyond its traditional military and automotive applications, establishing itself as a key solution in the fields of smart sensing, home automation, and non-invasive biomedical monitoring. Among the various architectures, continuous-wave (CW) radars offer an excellent balance between computational complexity, power consumption, and sensitivity in motion detection. This thesis presents the design, implementation, and validation of a custom embedded platform based on the Infineon BGT60LTR11AIP 60 GHz CW radar sensor of a custom embedded system to integrate and control the Infineon BGT60LTR11AIP CW radar sensor operating at 60 GHz. By utilizing the sensor’s Antenna-in-Package (AiP) technology, a printed circuit board (PCB) was developed to reduce electromagnetic interference and ensure the integrity of the power and output signals. Concurrently, the corresponding software driver was developed for interfacing with the processing unit, enabling the correct configuration of the radar’s operating parameters and the efficient acquisition of detection signals. The characterization results confirm the robustness of the hardware and validate the system for presence detection and micro-motion sensing. The development of this hardware-software platform lays the groundwork for future implementations focused on advanced signal processing algorithms, such as contactless monitoring of vital signs.
