Embodiment
Basic thought of the present invention is: on the electric-conductor (mainly being metalwork) that is arranged on the portable terminal body, the feeder line of mobile terminal antenna is set, and be connected respectively with distributing point or supply lead, earth point or the ground lead of mobile terminal antenna, and the length of set feeder line is more than 90mm.
For making the purpose, technical solutions and advantages of the present invention clearer, by the following examples and with reference to accompanying drawing, the present invention is described in more detail.
Below the design principle and the basic structure of plane inverse-F (PIFA, Radiation of Planar Inverted-F Antenna) antenna is introduced.Fig. 1 is for being arranged at PIFA Principle of Antenna structural representation in the portable terminal, as shown in Figure 1, the PIFA antenna comprises feeder line 14 and feed panel 13, for portable terminal, feed panel 13 promptly is the printed circuit board (PCB) (PCB, Printed Circuit Board) of portable terminal, wherein, parallel as the PCB of feed panel 13 in the plane at feeder line 14 places and the portable terminal, according to the design principle of PIFA antenna, two plane-parallel distances are about 6.5mm; Feeder line 14 is connected with feed source and earth point (line) on the electric panel 13 respectively by feed line 11 and earth connection 12; Wherein, feeder line 14 is the rectangular sheets with certain width and preseting length, its length be the antenna wireless signal of working wavelength 1/4th, regardless of the shape of feeder line, feeder line integral body all is in the same plane; Feeder line 14, feed line 11 all is the rectangular sheets with certain width and thickness with earth connection 12, and width wherein and two plane-parallel distances etc. are relevant, owing to designs such as this width belong to the PIFA Principle of Antenna, repeat no more here.Above-mentioned feed line 11 and earth connection 12 are all perpendicular to the plane at feeder line 14 places.
Above-mentioned feeder line is realized the purpose that portable terminal support multi-band signal receives, and can be set to a plurality of as required.A plurality of feeder lines can be arranged in same plane, also can belong to different planes, but these planes all are parallel to the feed face.
Fig. 2 is the schematic diagram of the metal edge frame of portable terminal casing of the present invention as the mobile terminal antenna feeder line, as shown in Figure 2, in this example, the casing of portable terminal (as fore shell) 24 is provided with ornamental metal edge frame 21, and on this metal edge frame 21, also be provided with connector (being equivalent to feed line and earth connection among Fig. 1) 22,27,28 perpendicular to plane, casing place, above-mentioned connector all is arranged at the casing inboard, to connect with the distributing point 23 (being connected with the feed source on the portable terminal pcb board) or the earth point 26 of mobile terminal antenna.Distributing point 23 and earth point 26 all are arranged on the portable terminal pcb board.Because metal edge frame 21 is a loop configuration, therefore, is provided with opening 25 in the bottom of metal edge frame 21, so that whole metal edge frame 21 is divided into two feeder lines under the prerequisite that keeps overall structure (needs of decoration are as attractive in appearance).Connector (earth connection among Fig. 1) 27,28 is arranged at the two ends of metal edge frame 21 openings 25 respectively.
Concrete, connector (feed line among Fig. 1) 22 is connected with the distributing point 23 of mobile terminal antenna, and connector 27,28 all is connected in earth point 26 connections of mobile terminal antenna.
Among the present invention, antenna in the portable terminal is supported multiband, as frequency ranges such as the GSM850, the GSM900 that mention in the background technology, DCS1800, PCS1900, W900, W1900, W2100.Antenna mode in the portable terminal is the PIFA antenna.Because the PIFA antenna technology is unusual mature technique, the present invention repeats no more its antenna structure and realizes principle.
Above-mentioned feeder line set on the metalwork of portable terminal body, length should be not less than 90mm, this considers that the resonance frequency in the PIFA antenna designs, so that the resonance frequency that this feeder line produces is lower than 850 megahertzes, with the minimum frequency of being supported less than mobile terminal antenna, thereby can not produce the influence of any radiation, thereby guarantee the performance of mobile terminal antenna frequency that mobile terminal antenna is supported.Concrete, it is 1/4 λ that the PIFA antenna requires feeder line length, and wherein, λ is a wavelength for the treatment of received signal, and the present invention is the feeder line that the electric-conductor on the portable terminal is set to antenna, causes the radiance influence to avoid its antenna to the configuration of portable terminal Central Plains.And the frequency that mobile terminal antenna is supported generally has GSM850, GSM900, DCS1800, PCS1900, W900, W1900, W2100, low-limit frequency is the 850M hertz, therefore, the objective of the invention is to make the electric-conductor on the portable terminal to form the antenna that reception is lower than the 850M signal as much as possible, the signal wavelength of 850M hertz signal correspondence is: 3 * 100000000m/s is divided by the 850M hertz, promptly getting its wavelength X is 0.352941m, and its 1/4 times is about 90mm.Above-mentioned feeder line length is long more, and the frequency of resonance is also just more little, and is also just more little to the ilities influence of mobile terminal antenna.
The design of above-mentioned feeder line, curve preferably is to satisfy the design length of this feeder line on limited portable terminal body.
Above-mentioned feeder line also can be arranged at other parts of portable terminal body, as it is first-class to be arranged at the back cabinet of portable terminal.
When the casing of portable terminal is metal material, also corresponding feeder line can be set on the casing of this portable terminal, concrete, can on the portable terminal casing, offer groove and form corresponding feeder line, the two ends of feeder line are connected on the distributing point of mobile terminal antenna and the earth point get final product.
Among the present invention, can be provided with at the two ends of feeder line and connect distributing point or earth point connector, lead-in wire (being equivalent to feed line, earth connection among Fig. 1 respectively) also can be set on distributing point and earth point, respective lead is connected with feeder line gets final product.
Design principle according to the PIFA antenna, the feed panel of PIFA antenna is provided with earth point and distributing point, the plane parallel at the feeder line place of this feed panel and antenna, distance between two parallel surfaces is generally greater than 6.5mm, and earth point and distributing point that the feeder line of antenna is connected on the feed panel promptly constitute the PIFA antenna.And feeder is connected by the connecting plate perpendicular to the feed panel with earth point and distributing point on the feed panel.In view of the above, the best plane with the feeder line place of the lead-in wire of above-mentioned distributing point and earth point is vertical.
When the lead-in wire of distributing point and earth point can be connected with feeder line, also can connector be set at the feeder line two ends.
The above is preferred embodiment of the present invention only, is not to be used to limit protection scope of the present invention.
