Fig. 2 is another schematic diagram of the utility model antenna radiator.
Fig. 3 is another schematic diagram of the utility model antenna radiator.
Embodiment
Below in conjunction with accompanying drawing and embodiment the utility model is described in further detail:
The utility model considers that the portable set inner space is narrow and small and irregular, so adopted Flexible Printed Circuit (FPC especially, Flexible Printed Circuit) as antenna substrate, the characteristics of Flexible Printed Circuit are soft and can be made into different shape, can farthest utilize the portable set inner space.
At the radiant body of Flexible Printed Circuit coppered wire as antenna, the radiant body of antenna is connected with feedback point on the portable set mainboard.
The length of described antenna radiator and antenna surrounding environment have determined the performance of antenna, and the length of antenna is long as far as possible, serve as preferred not to be shorter than 9 centimetres, reach 1.5 meters best results in theory.In addition, the metal of antenna periphery or other electric conductor will keep with a certain distance from antenna radiator, and it serves as preferred being not less than 3 millimeters with distance.
In preferred embodiment of the present utility model, the optimal way of three kinds of antenna cablings is provided, it serves as preferred being not less than 1 millimeter with the distance between line and the line.
(1) as shown in Figure 1, on Flexible Printed Circuit, walk out the radiant body of a snakelike circuit as antenna.
(2) as shown in Figure 2, on Flexible Printed Circuit, walk out the radiant body of a square waveform circuit as antenna.
(3) also can use mode snakelike and that the square waveform cabling combines.Shown in Figure 3, be example with the mobile phone,, according to space in the mobile phone, the radiant body of antenna 10 is walked the snake molded lines in the place of space broad, and the square wave line is walked in narrow place.Because the thickness of Flexible Printed Circuit can be accomplished 0.2 millimeter even 0.1 millimeter, so Flexible Printed Circuit can be by slot driller in the hand set machine shell or directly pasted fixing.
In preferred embodiment of the present utility model, the preferred connected mode between the feedback point on antenna and the equipment mainboard has two kinds:
(1) designs pad on the Flexible Printed Circuit, pass through welding manner with being connected of feedback point on the equipment mainboard.
(2) copper facing around the perforate in the middle of on the Flexible Printed Circuit, hole is fixedlyed connected with the feedback point on the equipment mainboard by screw.
In other preferred embodiments of the present utility model, the signal input pin of the as far as possible close broadcast receiver chip of the feedback point on the equipment mainboard.Feedback point one end is connected with antenna radiator on the equipment mainboard, and the other end must add T type match circuit, according to actual result the resonance point of antenna is adjusted.
