Abstract:
An electromagnetic coupler has a first conductor pattern and a second conductor pattern separated from the first conductor pattern that are formed in a first plane, a feeding pattern made of a conductor and being connected to a feeing system and a ground made of a conductor and being separated from the feeding pattern that are formed in a second plane, and linear conductors electrically connecting between the first conductor pattern and the feeding pattern, and between the second conductor pattern and the ground, respectively.
