Combo antenna module

A combo antenna module comprising:

• a magnetic sheet;
• a loop coil disposed on an upper surface of the magnetic sheet;
• an antenna sheet having an area smaller than an area of the magnetic sheet, and disposed on the upper surface of the magnetic sheet;
• and
• a step compensation sheet having an area smaller than the area of the magnetic sheet and disposed on the upper surface of the magnetic sheet,
• wherein the antenna sheet overlaps a part of the loop coil, and
• wherein the step compensation sheet is made of a resin material and is disposed to cover a region not overlapping the antenna sheet on the upper surface of the magnetic sheet
• wherein the antenna sheet comprises:
• a flexible base sheet having an area smaller than the area of the magnetic sheet, and overlapping a region in which a first end and a second end of the loop coil are disposed;
• an antenna pattern formed in a loop shape and disposed on an upper surface of the base sheet;
• a first connection pattern disposed on the upper surface of the base sheet, and electrically connected to the first end of the loop coil;
• and
• a second connection pattern spaced apart from the first connection pattern and disposed on the upper surface of the base sheet, and electrically connected to the second end of the loop coil, and
• wherein the first connection pattern and the second connection pattern are disposed in an inner region of the loop formed by the antenna pattern.
