Utility model content
The purpose of this utility model is the deficiency for prior art, provides a kind of coupled handset antenna, solve traditional FIFA, MOLOPOLE antenna because bandwidth is narrower, and the radiation efficiency of low frequency is lower, is difficult to realize the difficult problem that multiband meets OTA standard.
To achieve these goals, the technical scheme that the utility model provides is: a kind of coupled handset antenna, comprise the first radiant body, second radiant body and the 3rd radiant body, first radiant body to be positioned at below mainboard and with mainboard place plane orthogonal, second radiant body and the 3rd radiant body to be positioned at directly over mainboard and with mainboard place plane parallel, first radiant body and the second radiant body are positioned at two orthogonal planes, second radiant body and the 3rd radiant body are positioned at same plane, wherein, first radiant body is connected with mainboard distributing point, second radiant body and mainboard distributing point and present place and be connected, 3rd radiant body and mainboard are presented place and are connected, first radiant body is connected by mainboard distributing point with the second radiant body, realize a current circuit.
Described first radiant body is provided with fluting, regulates the size of the first radiant body and the size of fluting, realizes low-frequency resonant.
There is gap between described first radiant body and the second radiant body, regulate the gap spacing between the first radiant body and the second radiant body, in conjunction with the length of the first radiant body and the second radiant body, realize the expansion of low frequency bandwidth.
There is gap between described second radiant body and the 3rd radiant body, regulate the size of the second radiant body, realize high-frequency resonant, regulate the gap spacing between the second radiant body and the 3rd radiant body, in conjunction with the length of the 3rd radiant body, realize high frequency double resonance, expanding high-frequency bandwidth.
Compared with prior art, antenna is designed to three radiant bodies by the utility model, and wherein the first radiant body and the second radiant body lay respectively at two orthogonal planes, and two radiant bodies share the distributing point on mainboard; Second radiant body one end connects the distributing point on mainboard, and one end connects the feedback place on mainboard; 3rd radiant body and the second radiant body are at same plane; By the Coupling Design of three radiant bodies, increase the resonant bandwidth of antenna, improve the efficiency of antenna, thus realize the test request that multiband aerial meets OTA.
By following description also by reference to the accompanying drawings, the utility model will become more clear, and these accompanying drawings are for explaining embodiment of the present utility model.
Accompanying drawing explanation
Fig. 1 is an example structure schematic diagram of the utility model coupled handset antenna.
Embodiment
With reference now to accompanying drawing, describe embodiment of the present utility model, element numbers similar in accompanying drawing represents similar element.As mentioned above, as shown in Figure 1, a kind of coupled handset antenna that the present embodiment provides, comprise the first radiant body 11, second radiant body 15 and the 3rd radiant body 14, first radiant body 11 be positioned at mainboard 10 below and with mainboard 10 place plane orthogonal, second radiant body 15 and the 3rd radiant body 14 to be positioned at directly over mainboard 10 and with mainboard 10 place plane parallel, first radiant body 11 and the second radiant body 15 are positioned at two orthogonal planes, second radiant body 15 and the 3rd radiant body 14 are positioned at same plane, wherein, first radiant body 11 is connected with mainboard distributing point 13, second radiant body 15 and mainboard distributing point 13 and present place 12 and be connected, 3rd radiant body 14 and mainboard are presented place 12 and are connected, first radiant body 11 is connected by mainboard distributing point 13 with the second radiant body 15, realize a current circuit.
In the present embodiment, on described first radiant body, 11 are provided with fluting, regulate the length and width size of the first radiant body 11 and the size of fluting, realize low-frequency resonant, gap is there is between described first radiant body 11 and the second radiant body 15, regulate the gap spacing between the first radiant body 11 and the second radiant body 15, in conjunction with the length of the first radiant body 11 and the second radiant body 15, realize the expansion of low frequency bandwidth.
In the present embodiment, gap is there is between described second radiant body 15 and the 3rd radiant body 14, regulate the size of the second radiant body 15, realize high-frequency resonant, regulate the gap spacing between the second radiant body 15 and the 3rd radiant body 14, in conjunction with the length of the 3rd radiant body 14, realize high frequency double resonance, expanding high-frequency bandwidth, thus the requirement meeting multiband aerial.
Composition graphs 1 is known, and antenna is designed to three radiant bodies by the utility model, and wherein the first radiant body and the second radiant body lay respectively at two orthogonal planes, and two radiant bodies share the distributing point on mainboard; Second radiant body one end connects the distributing point on mainboard, and one end connects the feedback place on mainboard; 3rd radiant body and the second radiant body are at same plane; By the Coupling Design of three radiant bodies, increase the resonant bandwidth of antenna, improve the efficiency of antenna, thus realize the test request that multiband aerial meets OTA.
Comprehensive, the utility model well solves traditional FIFA, MOLOPOLE antenna because bandwidth is narrower, and the radiation efficiency of low frequency is lower, is difficult to realize the difficult problem that multiband meets OTA standard.Key point of the present invention is in the design of traditional antenna, add one directly from distributing point radiation fin out, by being coupled of this radiation fin and conventional radiation sheet, increase antenna is in the bandwidth of low frequency and high frequency, improve the efficiency of antenna, improve the received signal quality of mobile phone.
