Abstract
A double-frequency aerial comprises a plaque, wherein, the plaque is provided with a first surface and a second surface opposite to each other; the first surface is arranged with a first and a second radiation parts with the second radiation part separated from the first radiation part; the second surface is disposed with an earthing part; between the first radiation part and the earthing part is provided a first conductive connecting part, while between the second radiation part and the earthing part, a second conductive connecting part. Thereby, double-frequency receiving function is realized through providing two radiation parts on one plaque with low manufacture and assembling cost of the aerial.
Description
[Ji Intraoperative field]
The utility model is a kind of antenna, the little and cheap dual-band antenna of particularly a kind of volume.
[Bei Jing Ji Intraoperative]
Because the product of wireless transmission is universal day by day, the user can not be subjected to environmental limit to utilize radio transmitting device, transmit or receive data and information, for radio transmitting device, no matter be personal digital assistant, mobile phone or notebook computer or the like, antenna is considerable assembly in the radio transmitting device, because the quality of antenna has considerable influence to the quality of wireless transmission and reception.
Antenna comprises the antenna of single frequency band and the antenna of two-band, and the form that the antenna of existing two-band need be arranged to two antenna monomers to separate usually thus, can cause volume bigger than normal, and in addition, manufacturing and assembly cost are higher.
[summary of the invention]
The dual-band antenna that provides a kind of volume little and cheap is provided main purpose of the present utility model.
For reaching above-mentioned purpose, the utility model provides a kind of dual-band antenna, and it comprises a substrate, and this substrate is provided with first surface and second surface, and first surface is relative with second surface; And the first surface in this substrate is provided with one first Department of Radiation and one second Department of Radiation, and second Department of Radiation and first Department of Radiation are separated; And be provided with a grounding parts in the second surface of this substrate; And between first Department of Radiation and grounding parts, be provided with one first conductive connection part; And between second Department of Radiation and grounding parts, be provided with one second conductive connection part.
Xiang is in Xian You Ji Intraoperative, and the volume of the utility model dual-band antenna is enough little, and it is provided with two Departments of Radiation realizing the double frequency receiving function on same substrate, and does not need two antenna monomers are made respectively and assembled, and cost is lower.
