| 摘要 |
An wireless communication device with an antenna (400) for sending and receiving signals in a plurality of frequency bands generates a plurality of resonances in the plurality of frequency bands and includes a first radiating element (402) that generates a first resonance in a first frequency band, a second radiating element (404), coupled to and extending at an angle from the first radiating element (402), that generates a second resonance in the first frequency band, and a third radiating element (406), coupled to and extended at an angle from the first radiating element (402). A capacitive coupling between the second radiating element (404) and the third radiating element (406) generates a loop with a third resonance in the first frequency band, and the third radiating element (406) generates a fourth resonance in a second frequency band independent of the loop at the second frequency band.
