Embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, be clearly and completely described the technical scheme in the utility model embodiment, obviously, described embodiment is only the utility model part embodiment, instead of whole embodiments.Based on the embodiment in the utility model, those of ordinary skill in the art are not making other embodiments all obtained under creative work prerequisite, all belong to the scope of the utility model protection.
Refer to Fig. 1 ~ 4, in the utility model embodiment, a kind of miniaturized built-in child mobile phone antenna, comprises circuit board, feedback pin and antenna metal pattern; Circuit board comprises board substrate and board metal layer pattern; Board metal layer pattern comprises ground floor B3, ground connection sensing chip D2 and holding wire pad D3; Board substrate comprises the first headroom B1, the second headroom D5 and board substrate B2; Antenna metal pattern comprises antenna top layer pattern A1 and connecting pin pattern A3; Antenna top layer pattern A1 comprises metal pattern A101 ~ A106; Described antenna top layer pattern A1 bottom is connected with holding wire pad D3 with feedback pin shell fragment F2 by connecting pin pattern A3; Described ground floor B3 is arranged on board metal layer pattern lowermost end; Described ground connection sensing chip D2 is arranged on board metal patterned layer front center.
Further, described antenna top layer pattern A1 is provided with a path radiation loop, letter is from A1 through A101 to A102, is then connected to A6, and whole loop forms quarter-wave loop aerial, produces low-frequency resonant.
Further, signal is connected to A3 from D3 through F2, then by antenna top layer pattern A1 radiation; A101 and ground connection sensing chip D2 produces an electric capacity, produces a high-frequency resonant; A102 and ground connection sensing chip D2 produces an electric capacity, and have electromagenetic wave radiation at the first headroom place, the two produces another high-frequency resonant jointly;
A103 and A104, in metallic profiles sideline X304, produces an inductance capacitance with A106, affects the resonance of two low frequencies.
The gap of A105 and A106 between the X5061 of metallic profiles sideline forms slot antenna, and the length in gap and width determine the performance affecting the resonance of two low frequencies.
Operation principle of the present utility model is: signal is connected to metal pattern from holding wire pad through the second connecting pin, then by the radiation of antenna top layer pattern.Metal pattern is provided with a path radiation loop, signal be from the second connecting pin through the first metal pattern to the second metal pattern, be then connected to the first connecting pin.Whole loop forms the shorted section of PIFA antenna.First metal pattern connects the 4th metal pattern, and the 4th metal pattern is end to end to the 7th metal pattern, and produce a low-frequency resonant, whole length is quarter-wave; First metal pattern connects one article of finedraw of being separated by between the 4th metal pattern, produces one section of high-frequency resonant.8th metal pattern is connected on the first metal pattern, and produces another section of high-frequency resonant with the 7th connecting pin.3rd metal pattern connects the 3rd connecting pin, and the second connecting pin produces a parasitic capacitance, thus produces the 3rd high-frequency resonant.The ground of five metals metal patterns and the first headroom edge attachments produces certain electric capacity, plays and regulates antenna match effect.
