Abstract
A communication device includes a nonconductive housing, a cable, an antenna structure, and a signal source. The nonconductive housing has a hollow structure. The cable is coupled to the signal source. The cable includes a signaling conductor and a grounding conductor. The antenna structure includes an antenna body and an enclosed radiation element. The antenna body is coupled to the signaling conductor. The antenna body is disposed outside the nonconductive housing. The enclosed radiation element is coupled to the grounding conductor. The enclosed radiation element is disposed inside the nonconductive housing.
Claims20
A communication device, comprising:
- a nonconductive housing, having a hollow structure;
- a signal source;
- a cable, coupled to the signal source, and comprising a signaling conductor and a grounding conductor;
- and
- an antenna structure, comprising:
- an antenna body, coupled to the signaling conductor, wherein the antenna body is disposed outside the nonconductive housing;
- an enclosed radiation element, coupled to the grounding conductor, wherein the enclosed radiation element is disposed inside the nonconductive housing.
An antenna structure, comprising:
- an antenna body, coupled to a positive electrode of a signal source;
- and
- an enclosed radiation element, coupled to a negative electrode of the signal source;
- wherein the antenna structure covers a low-frequency band and a high-frequency band;
- wherein a sum of a length of the antenna body and a length of the enclosed radiation element is substantially equal to 0.4 wavelength of the low-frequency band.
