PURPOSE: An internal antenna apparatus is provided to minimize the coating of a radiation material by forming an opening in a part of the flexible substrate. CONSTITUTION: An internal antenna apparatus includes a flexible substrate(100). The flexible substrate is formed with a conductive material. The flexible substrate is mounted in the outer circumference of a housing(120). The flexible substrate acts as the radiator of an antenna. A plurality of openings(150) are formed over 20-80% of the total area of the flexible substrate.
