Abstract
A plane antenna relates to an antenna, comprising a reversed F shaped plane patch antenna which is printed with a zigzag line, wherein the end portion of the back F shaped plane patch antenna is provided with a short circuit hole and a feed hole, which is characterized in that the middle portion of the reversed F shaped plane patch antenna is provided with a gap, the gap extends to a side of the reversed F shaped plane patch antenna, the gap is L shaped, the gap extends to the inner side portion near the zigzag line from the antenna middle portion, then vertically turns to the side of the antenna, and the zigzag line is connected on the end of the reversed F shaped plane patch antenna. The utility model has simple structure, small width, and low cost, causes the small sized plane antenna have the multiple frequency sectors performance ability, which is suitable for each kind of mobile terminal products, wireless palmtop computers and wireless intelligent phones.
Description
[technical field]
The utility model relates to antenna, relates in particular to a kind of flat plane antenna.
[background technology]
In the prior art, traditional whip antenna such as unipole antenna and helical antenna has been widely used in the mobile phone, because the miniaturization of equipment such as mobile phone, and because of the demand of beautifying of outward appearance, this antenna is little by size, the unobtrusive small-sized built-in aerial of profile replaces, wherein, some plane patch antennas, obtained using comparatively widely as anti-F type plane patch antenna, but anti-F type plane patch antenna great majority in existing design only are suitable for the one-segment running, and that can not satisfy that quick growth owing to wireless telecommunication system produces possesses the demand of multiband operating capability for this small-sized flat plane antenna.
[summary of the invention]
The utility model provides a kind of flat plane antenna, to solve the problem that the middle-size and small-size flat plane antenna of prior art does not possess the multiband operating capability.
The technical scheme that the utility model adopted is: this flat plane antenna, comprise the anti-F type plane patch antenna that is printed with the extensions of wriggling, described anti-F type plane patch antenna end is provided with short circuit hole and power feed hole, it is characterized in that: described anti-F type plane patch antenna middle part offers slit, and this slit extends to the side of anti-F type plane patch antenna;
Described slit is the L type;
Described slit is by the inside portion that extends in the middle part of the described antenna near the extensions of wriggling, the side of the described antenna of vertical duction again;
The described extensions of wriggling are connected the end of anti-F type plane patch antenna.
The beneficial effects of the utility model are: in the utility model, anti-F type plane patch antenna middle part offers slit, this slit extends to the side of anti-F type plane patch antenna, like this, in fact this slit has produced this antenna separation is the effect with two microstrip lines, and two microstrip lines are controlled exciting of two different resonance frequencys, wherein, the microstrip line that is connected with the extensions of wriggling can be used for relative low band signal, and like this, the utility model has just possessed the multiband operating capability; Slit adopts the L type, and the inside portion that extends to the close extensions of wriggling by the antenna middle part, vertical duction is extended down to the side of antenna again, can be so that the design of antenna and manufacturing, further improve practicality of the present utility model, the extensions of wriggling are connected the end of anti-F type Ping Mian Stickers chip antenna, can be used as the area that reduces total.Therefore, the utility model is simple in structure, and width is tiny, and cost is low, makes small-sized flat plane antenna possess the multiband operating capability, is applicable in various portable terminal products, wireless Palm Pilots and the intelligent wireless phone.
