Abstract
A wireless module includes a wireless module main body including a first antenna on a first insulating substrate, and a coupler including a second antenna on a second insulating substrate arranged so as to face the first insulating substrate, wherein a connection terminal to which an external antenna is connectable is formed in the second insulating substrate, the connection terminal being connected to a feeding point for the second antenna, individual portions of the conductor patterns in the first antenna and the second antenna are configured so as to face each other, a resonant frequency of the second antenna is set to be higher than a resonant frequency of the first antenna, and the resonant frequency of the second antenna is set so that a transmission frequency characteristic from the first antenna to the second antenna matches a frequency characteristic of the resonant frequency of the first antenna.
