Abstract
An antenna structure of reduced size but able to cover first, second, and third LTE-A bands together with WI-FI and BLUETOOTH frequencies includes a metal frame defining at least two gaps. The gaps extend and pass completely through the metal frame, and divide the metal frame into radiating portions. At least one feeding portion is electrically coupled to each radiating portion. Each radiating portion can simultaneously activate first, second, and third operating modes for the radiation of signals in first, second, and third frequency bands.
