Antenna structure for a near-field communication device

A short-range communications-enabled device, comprising:

• a housing;
• a radio transmitter and receiver for respectively sending and receiving RF signals over a wireless communication network;
• a short-range communication component located in the housing for establishing short range communication with a second short-range enabled device that is located within short range, said short-range communication component includes an antenna element for generating an electromagnetic signal that is used to establish the short range communication and a receiver circuit for extracting information obtained from the second short-range enabled device;
• and
• a shielding arrangement located in the housing and disposed between the antenna element and the receiver circuit such that a gap that is at least 0.5 mm in width is maintained between the antenna element and the shielding arrangement.

A mobile communications device, comprising:

• a housing;
• a radio transmitter and receiver for respectively sending and receiving RF signals over a wireless communication network;
• a short-range communication component located in the housing for establishing short range communication with a second short-range enabled device that is located within short range, said short-range communication component includes an antenna element for generating an electromagnetic signal that is used to establish the short range communication and at least one printed circuit board on which active electronic elements are located to process short range communication signals received from the second short-range enabled device that is located within short range;
• a high magnetic permeability sheet located in the housing and disposed between the antenna element and the at least one printed circuit board;
• and
• a nonconductive material located between the antenna element and the high magnetic permeability sheet.
