摘要： A tri-band antenna for noncellular wireless applications is provided. The antenna (100) comprises: a first radiating arm (101) enabled for generating a first resonance in a first frequency band, the first radiating arm (101) further enabled for connection to an antenna tuning circuit (903); the first radiating arm (101) comprising a capacitive coupling structure (108); a coupling arm (105) separated by a gap from the first radiating arm (101); a second radiating arm (102) enabled for generating a second resonance in a second frequency band lower than the first frequency band, the second radiating arm (102) connected to the coupling arm (105) such that the second radiating arm (102) is capacitively coupled to the first radiating arm (101); and a third radiating arm (103) enabled for generating a third resonance in a third frequency band lower than the second frequency band, the third radiating arm (103) connected to the coupling arm (105) such that the third radiating arm (103) is capacitively coupled to the first radiating arm (101).
