    摘要: An antenna structure of few components and reduced size which functions by switching between components to achieve radiation in three different frequency bands includes two radiating portions, a feeding portion, a matching circuit, and a first switching circuit. With the first switching circuit closed, current flows along a first radiating portion to activate a first frequency band. A second radiating portion obtains the current from the first switching circuit by coupling with the first radiating portion, to activate a second frequency band. Current in the first radiating portion can activate a third frequency band. With the first switching circuit open, current in the first radiating portion activates radiation in the first frequency band. The second radiating portion can radiate in second frequency band by coupling current from the first radiating portion. Frequency multiplication of the first frequency band can activate the third frequency band.

    摘要: An antenna structure includes a housing, four feed sources, a first radiator, a second radiator, and a third radiator. The housing includes a first radiating portion and a second radiating portion. The first to third radiators are positioned in the housing. The first radiator is spaced apart from the second radiator. The four feed sources respectively connect to the first radiating portion, the second radiating portion, the first radiator, and the third radiator. The first radiating portion activates a first operation mode and a second operation mode. The second radiating portion activates a third operation mode. The first to third radiators activate a fourth operation mode, a fifth operation mode, and a sixth operation mode.
