Abstract
The invention provides a SIM card IC module and a SIM card having a small antenna gain change. A SIM card 10 includes an IC module 11 including a circuit section 18 having a plurality of electronic components 16 mounted on a mounting surface 14A of a board 14, and an antenna 20 connected to the circuit section 18, and a plate-like base member 12 in which a recessed portion 22 for accommodating the circuit section 18 is provided. The antenna 20 is arranged to be substantially parallel to the mounting surface 14A, and has a three-dimensional structure arranged at a position shifted by a predetermined dimension from the mounting surface 14A along a thickness direction of the board 14.
Claims22
A SIM card IC module comprising a board,
- a circuit section having a plurality of electronic components mounted on a mounting surface of the board, and an antenna connected to the circuit section, and constituting a SIM card by accommodating the IC module in a recessed portion of a base member formed in a plate shape,
- wherein the antenna is arranged to be parallel to the mounting surface and arranged at a position shifted from the mounting surface by a predetermined dimension along a thickness direction of the board.
A SIM card having an IC module including a board and a circuit section with a plurality of electronic components mounted on a mounting surface of the board, and a plate-like base member in which a recessed portion which accommodates the circuit section is provided, the SIM card comprising:
- a terminal portion connected to the circuit section and exposed on a surface of the IC module;
- and
- an antenna connected to the terminal portion, arranged to be parallel to the mounting surface, and arranged at a position shifted from the mounting surface by a predetermined dimension along a thickness direction of the board, wherein the antenna is a loop antenna looping in a plane intersecting with the mounting surface and having a section substantially parallel to the mounting surface.
A SIM card IC module receivable in a SIM base plate, comprising:
- a board;
- a circuit section having a plurality of electronic components mounted on a mounting surface of the board, wherein the mounting surface has a first side, the electronic components being mounted on the first side of the mounting surface, and a second side opposite to the first side;
- and
- an antenna connected to the circuit section, wherein the antenna comprises a first segment running, on the first side of the mounting surface, spaced apart by a predetermined distance from and in substantially parallel to the mounting surface and a second segment running on the second side of the mounting surface.
A SIM card comprising:
- an IC module comprising a board and a circuit section with a plurality of electronic components mounted on a mounting surface of the board, wherein the mounting surface defines a first side, the electronic components being mounted on the first side of the mounting surface, and a second side opposite to the first side;
- a base plate to which the IC module is attached, wherein the base plate is formed with a recess for receiving the circuit section;
- and
- an antenna connected to the circuit section, wherein the antenna comprises a first segment running, on the first side of the mounting surface, spaced apart by a predetermined distance from and in substantially parallel to the mounting surface and a second segment running on the second side of the mounting surface.
