Embodiment
As shown in Figure 1; For but the sketch map of the portable electronic equipment of the antenna structure of phase mutual interference between suppressing antenna is installed in this execution mode; Antenna structure 100 in this portable electronic equipment 1 comprises one first antenna 10 and one second antenna 20; This first antenna 10 and second antenna 20 all are arranged on the madial wall of shell 30 of portable electronic equipment; This first antenna 10 is connected to the load point and the earth point of this first antenna 10 on the circuit board 50 of portable electronic equipment 1 through two metal clipss 40, this second antenna 20 is connected to the load point and the earth point of this second antenna 20 on the circuit board 50 of portable electronic equipment 1 equally through two metal clipss 40.In this execution mode; This first antenna 10 and second antenna 20 are the antenna of FPC (soft board) type; Because first antenna 10 and second antenna 20 distance at interval are closer, so the interference between two antennas is bigger, in order to weaken two interference between antenna; This antenna structure 100 also comprises a T type metal structure 60 that is arranged between first antenna 10 and second antenna 20; This T type metal structure 60 comprises horizontal component 601 and vertical part 602, and wherein, vertically part 602 ends are electrically connected to the circuit board 50 of portable electronic equipment.This horizontal component 601 can form an inductive sensor under electromagnetic effect; This vertical part 602 can form an inductance capacitance under electromagnetic effect; This inductive sensor and this inductance capacitance have the effect of filtering; When the arbitrary side in first antenna 10 and second antenna 20 produces interference signal, can this interference signal be directed at circuit board 50 through copper sheet structure 60, thereby can effectively weaken the interference between first antenna 10 and second antenna 20.
In this execution mode, this first antenna 10 is the gps antenna of FPC (soft board) type, and second antenna 20 is FPC (soft board) type Wi-Fi antenna.What the material of this metal clips 40 and T type metal structure 60 was preferable is copper, and in other embodiments, the material of this metal clips 40 and T type metal structure 60 can be iron, aluminium, silver etc.
In other embodiments, if the inner walls of portable electronic equipment 1 is provided with plural antenna, and antenna is between any two through being provided with mode that T type metal structure weakens inter-antenna interference also within the scope that the present invention protected.
Fig. 2 is the interference analysis figure between first antenna 10 and second antenna 20 when between first antenna 10 and second antenna 20, T type metal structure 60 not being set in the portable electronic equipment 1.The frequency range of the transverse axis expression signal among the figure, the longitudinal axis is represented the isolation of interference signal.In this execution mode, the signal band limits of analysis is 1.2GHz-3.0GHz, is spaced apart 200MHz; The scope of the corresponding isolation of signal band limits is-80dB-20dB to be spaced apart 10dB, wherein; Primary importance 21 is that first antenna 10 is the corresponding isolation of gps antenna; Be-8.324dB, the second place 22 is that second antenna 20 is the corresponding isolation of Wi-Fi antenna with the 3rd position 23, is respectively-11.78dB and-13.50dB.
Fig. 3 is portable electronic equipment 1 interference analysis figure between first antenna 10 and second antenna 20 when between first antenna and second antenna, adding T type metal structure 60.The signal band limits of analyzing is 1.2GHz-3.0GHz; Be spaced apart 200MHz, the scope of the corresponding isolation of signal band limits is-80dB-20dB to be spaced apart 10dB; Wherein primary importance 31 is that first antenna 10 is the corresponding isolation of gps antenna; Be-14.98dB, the second place 32 is that second antenna 20 is the corresponding isolation of Wi-Fi antenna with the 3rd position 33, be respectively-22.92dB and-24.78dB.It is thus clear that after having used T type metal structure 60 between first antenna 10 and second antenna 20, effectively reduced the interference between first antenna 10 and second antenna 20.
Be appreciated that the above execution mode only supplies to explain the present invention's usefulness, and be not limitation of the present invention.The variation that the those of ordinary skill in relevant technologies field is made in the corresponding techniques field according to the present invention should belong to protection category of the present invention.
