The vital sign detection device of the present invention includes one or more sensors, which can detect a plurality of vital sign signals of a test subject in a non-contact manner, and output corresponding a plurality of vital sign information, thereby achieving fast and accurate vital sign detection. The invention also relates to a combined multi-functional detection device, which includes a camera, a radar sensor, an infrared sensor and a sensor driving unit, used for measuring vital signs. The invention also provides a non-contact blood pressure measurement method and device. The method includes receiving radar echoes and video signal streams at first and second parts, extracting first and second pulse wave signals therefrom, obtaining a measured pulse wave transit time, matching the measured pulse wave transit time with a reference pulse wave transit time, and obtaining a blood pressure value.

Vital sign detection apparatus and system and data processing method

A multiple frequency band antenna is disclosed involving a first resonant portion tuned to a low frequency band; a second resonant portion tuned to a first high frequency band at frequencies higher than the low frequency band; a third resonant portion tuned to a second high frequency band at frequencies higher than the low frequency band and substantially different from the first high frequency band; and a first conductor portion forming part of the first resonant portion and the second resonant portion, the first conductor portion having a grounding point, a feeding point for providing an input signal to at least one of the first resonant portion and the second resonant portion and for receiving an output signal from at least one of the first resonant portion and the second resonant portion, and a second conductor portion electrically connected to the feeding point wherein the third resonant portion is electrically connected to the second conductor portion.
