1. A detection device for detecting a human body portion, comprising:
a plurality of capacitive sensors, detecting first information of the human body portion in a first direction, and detecting second information of the human body portion in a second direction;
a transmission antenna;
a reception antenna;
a radar module, using the transmission antenna to transmit a radar signal to the human body portion, and using the reception antenna to receive a reflection signal from the human body portion, wherein the radar module detects third information of the human body portion in a third direction according to the reflection signal;
a carrier element, wherein the capacitive sensors, the transmission antenna, and the reception antenna are disposed on the carrier element;
a processor, estimating status information of the human body portion according to the first information, the second information, and the third information; and
an antenna cover, covering the transmission antenna and the reception antenna;
wherein the antenna cover comprises a conductive layer and a nonconductive housing;
wherein the conductive layer comprises a signal radiation region and a signal cut-off region;
wherein a plurality of slots are formed and periodically arranged in the signal radiation region of the conductive layer.
