摘要: Disclosed is an electronic scanning array antenna which can be used as a UWB radar having an occupied band of not less than 500 MHz. An impulse generator is connected to each of a plurality of antenna elements constituting the electronic scanning array antenna, and a transmission trigger time to each of the impulse generators connected to the antenna elements is changed, whereby the phase of radio waves emitted from an antenna is equivalently changed. Moreover, a transmission trigger repletion interval is changed to thereby control a direction of a beam emitted from the array antenna. As means of changing a transmission trigger timing to each of the impulse generators connected to the antenna elements, a method of changing a frequency of a transmission trigger pulse and a method of changing a pulse position are adopted.

摘要: The present invention provides a vital signal detection device of a portable and non-contact type that can independently acquire vital information such as body temperature, respiratory rate, and heart rate simultaneously.
The present invention includes: an antenna unit provided with a planar antenna of a MIMO radar on a front surface; and a display unit including a display panel on the front surface. The antenna unit is combined with the display unit or the display unit is combined with the antenna unit in a rotatable manner so that, from a state where the planar antenna and the display panel face in a direction ahead of the front surface, the planar antenna is turned to be directed to a direction of a back surface of the display unit opposite from the display panel. The portable non-contact vital signal detection device detects a vital signal on a side ahead of the front surface and a vital signal on a side in the direction of the back surface opposite from the front surface.-
