Abstract
A wireless communication apparatus in one embodiment includes a bag body and a radio frequency device. The bag body has at least a first slot, which extends to an edge of the bag body. The radio frequency device including a wireless integrated circuit chip is for radio-frequency signal transmission or receiving, and is disposed across a portion of the first slot and coupled to two connection ends of the bag body so that the bag body between the two connection ends serves as an inductance circuit. The inductance circuit of the two connection ends of the bag body is based on metallic material. An impedance of the inductance circuit is for conjugate matching with that of the radio frequency device and is determined according to a plurality of geometric parameters including: a distance from the edge to the wireless integrated circuit chip, and size of the first slot.
