Dual-band antenna of wireless communication apparatus

A dual-band antenna of a wireless communication apparatus, comprising:

• a first radiation part, configured to operably receive or transmit signals at a first frequency band;
• a second radiation part, configured to operably generate a coupling effect together with the first radiation part to receive or transmit signals at a second frequency band having a center frequency lower than a center frequency of the first frequency band, wherein the second radiation part comprises multiple radiation sections, and at least one of the multiple radiation sections is positioned on a first plane;
• a feeding element, coupled with the first radiation part, for coupling with a signal receiving terminal of the wireless communication apparatus;
• and
• a shorting element, coupled with the second radiation part, for coupling with a fixed-voltage region of the wireless communication apparatus;
• wherein the first radiation part does not physically contact with the second radiation part, and at least a portion of the first radiation part is not positioned on the first plane.
