Abstract

This chapter presents a novel antennae system for human vital signs detection. In this work, system working principles and different types of patch antennae are introduced, along with the measurement set up of the vital signs detecting radar sensor system. A wide band (from 900 MHz to 12 GHz) patch antennae system with beam-enhanced capacity is developed in FR4 substrate. This substrate has dielectric constant 4.4 and 1.2 mm of height. To reduce the size of the antennae system, a 3D-orthogonal structure was utilized to design the transmitting and receiving antennae. The multi-patch elements transmitting antenna was placed orthogonally with the receiving antenna to decrease the size of the antennae system. Moreover, the bandwidth and the directional capacity of the antennae were put in high priority to identify the human’s chest displacement at different frequencies, from L band to the X band. The measurement outcome shows that human vital signs could be revealed by the proposed 3D antennae system.
