Abstract
To provide a wireless communication module that implements the function to detect a human body in a conserved space and is capable of detecting a proximity to human bodies with high accuracy. A wireless communication module includes an antenna unit and a proximity detector which detects that a human body has approached the module. The antenna unit includes an antenna and a first filter which is comprised of distributed constant elements. The proximity detector for human bodies uses the antenna and the first filter as an electrode to detect capacitance.
