Antenna

摘要

An antenna for receiving radio signals of at least a first frequency band and a second frequency band includes a grounding unit for providing grounding, a connecting unit electrically connected to a first terminal of the grounding unit, a feeding terminal, formed on the connecting unit, for transmitting the radio signals of the first frequency band and the second frequency band, a first radiating element electrically connected between the connecting unit and a second terminal of the grounding unit, and a second radiating element electrically connected between the connecting unit and a third terminal of the grounding unit. Lengths of signal routes from the feeding terminal through the first radiating element and the second radiating element to the grounding unit are substantially equal to a half wavelength of the radio signals of the first frequency band and a half wavelength of the radio signals of the second frequency band, respectively.

1. An antenna for transmitting and receiving radio signals of at least a first frequency band and a second frequency band, comprising:
a grounding unit, for providing grounding; a connecting unit, electrically connected to a first terminal of the grounding unit; a feeding terminal, formed on the connecting unit, for transmitting the radio signals of the first frequency band and the second frequency band; a first radiating element, electrically connected to the connecting unit and a second terminal of the grounding unit, wherein a length of a signal path from the feeding terminal through the connecting unit and the first radiating element to the second terminal of the grounding unit is substantially equal to a half wavelength of radio signals at the first frequency band, to form the first radiating element used for transmitting and receiving the radio signals of the first frequency band; and a second radiating element, electrically connected to the connecting unit and a third terminal of the grounding unit, wherein a length of a signal path from the feeding terminal through the connecting unit and the second radiating element to the third terminal of the grounding unit is substantially equal to a half wavelength of radio signals at the second frequency band, to form the second radiating element used for transmitting and receiving the radio signals of the second frequency band.
