1. A radio-frequency (RF) transceiver device, capable of reducing a specific absorption rate (SAR), comprising:
an antenna, comprising:
a grounding element, extending along a first direction on a first plane; anda radiating element, comprising:
a first branch, extending along the first direction, electrically connected to the grounding element;a second branch, extending along the first direction;a third branch, electrically connected to and perpendicular to the first branch and the second branch; anda fourth branch, extending along the first direction, electrically connected to the third branch; and a SAR suppression unit, for reducing the SAR of the antenna; wherein the SAR suppression unit extends along the first direction and along an edge of the radiating element adjacent to the SAR suppression unit; wherein the SAR suppression unit is separated from the edge of the radiating element by a gap; wherein the antenna operates in a plurality of bands, and a length of the SAR suppression unit is equal to a quarter of wavelength corresponding to a lowest band within the plurality of bands; wherein the SAR suppression unit is not electrically connected to the radiating element and the grounding element; wherein the radiating element is positioned between the grounding element and the SAR suppression unit. |
