Classification: CPC H | IPC H

Claim 14:
15. A wireless communication device comprising:
a wireless communication module; and
a battery configured to supply power to the wireless communication module,
wherein the wireless communication module comprising:
an antenna comprising a resonant structure and a first feeding line; and
a radio frequency (RF) module configured to be electrically connected to the first feeding line,
wherein the resonant structure comprises:
a conducting portion extending in a first plane, and the conducting portion comprising a plurality of first conductors;
a ground conductor extending in the first plane, and being separated from the conducting portion in a third direction, the third direction intersecting the first plane;
a first number of connecting conductors extending from the ground conductor toward the conducting portion, the first number being three or more; and
a third number of capacitive portions configured to capacitively connect a pair of first conductors of the plurality of first conductors, the pair of first conductors being separated by at least a corresponding gap, the third number being one or more;, wherein at least two conductors of the plurality of first conductors are connected to different connecting conductors;
wherein two connecting conductors of the first number of connecting conductors are part of a first connecting pair aligned in a first direction in the first plane;
wherein two connecting conductors of the first number of connecting conductors are part of a second connecting pair aligned in a second direction in the first plane and intersecting the first direction;
wherein the resonant structure is configured to resonate at a first frequency in a first current path;
wherein the resonant structure is configured to resonate at a second frequency in a second current path;
wherein the first current path comprises the ground conductor, the conducting portion, at least a first capacitive portion of the third number of capacitive portions, and the first connecting pair;
wherein the second current path comprises the ground conductor, the conducting portion, and the second connecting pair; and
wherein the first feeding line is configured to electromagnetically connect to the conducting portion.
