Abstract
The invention provides a Loop antenna system with gaps for radiation. The Loop antenna system comprises a metal frame. The two gaps are formed in the bottom edge of the metal frame. The interior of the metal frame is divided into a clearance zone and a main land portion. The clearance zone is located on the side, close to the gaps, in the metal frame and the main land portion is connected with the metal frame. The two ends of the portion, between the two gaps, of the metal frame are connected with a feed source and the main land portion respectively through antenna portions, so that a Loop antenna structural mode is formed and the antenna portions are located in the clearance zone. According to the Loop antenna system, the metal frame of a mobile terminal serves as a part of an antenna to be used in the radiation process. On one hand, radiation is conducted by the two gaps and the Loop antenna together so that the high-radiation antenna system can be formed and have the advantage that the bandwidth is increased; on the other hand, due to the facts that the two gaps are formed in the bottom edge and the Loop antenna is low in sensitivity, the Loop antenna system has the advantages of being low in sensitivity and high in signal strength.

Embodiment
Referring to the accompanying drawing that the embodiment of the present invention is shown, the present invention below will be described in more detail.But the present invention can be with many multi-form realizations, and should not be construed as the restriction of the embodiment being subject in this proposition.On the contrary, it is abundant and complete open in order to reach proposing these embodiment, and makes those skilled in the art understand scope of the present invention completely.In these accompanying drawings, for clarity sake, may amplify size and the relative size in layer and region.
With reference to figure 1-6, the invention provides the Loop antenna system of a kind of gap participation radiation, for transmitting and receiving wireless signal on mobile terminal device, mainly comprise metal edge frame and Loop antenna.The present invention adopts and on metal edge frame, offers gap, and the antenna form that metal edge frame is combined with Loop antenna, metal mobile device signal difference in prior art, the poor problem of antenna performance are solved, because this system power is evenly distributed, greatly reduce SAR(electro-magnetic wave absorption ratio simultaneously) risk.The situation that is mobile phone with regard to mobile terminal device is below elaborated.
Concrete, the Loop antenna system that this gap participates in radiation comprises a metal edge frame, as shown in Figure 1-2, the rectangular shape of this metal edge frame, this metal edge frame can directly use as mobile phone frame; The base of metal edge frame offers two gaps, be respectively the first gap 6 and the second gap 7, make metal edge frame be divided into two parts, a part is the bottom side metal edge frame 4 between the first gap 6 and the second gap 7 on metal edge frame base, and another part is made up of the top side metal edge frame 1 being connected together, left side metal edge frame 2 and right side metal edge frame 3; Metal edge frame inside is provided with headroom district 5 and main ground part 8, and headroom district 5 is positioned at a side of bottom side metal edge frame 4, and the upper side edge of main ground part 8 is connected and is grounded with side metal edge frame 1, left side metal edge frame 2, right side metal edge frame 3 respectively with left and right side; Part 8 can, for having metal or the pcb board etc. to electric conductivity, not be restricted herein wherein mainly.
In the present embodiment, the first gap 6 and the second gap 7 are arranged on the base of metal edge frame, on the base of mobile phone, because gap is very responsive, right overhead or hand contact or while approaching gap, near dielectric constant sudden change gap can cause RL(return loss) skew, thereby (" hand machine head fingerprint " refers to the model of laboratory test for phantom bead and staff to cause hand machine head fingerprint, in experimentation, mobile phone is placed on to model head and tests on hand) performance fast-descending, user can feel that mobile phone signal is poor intuitively, therefore the present invention is opened in the first gap 6 and the second gap 7 on the base of metal edge frame, can greatly reduce head, the impact that hand brings to antenna performance.
In the present embodiment, all there is coupling in 6 places, the first gap and 7 places, the second gap, and therefore the first gap 6 and the second gap 7 can produce radiation, participates in antenna work.Wherein, the size in the first gap 6 and the second gap 7 is larger, and loss (this loss specifically refers to reflection and the consumption of electromagnetic energy) bandwidth and efficiency less, antenna is higher; In the present embodiment, preferably the width in the first gap 6 and the second gap 7 is more than or equal to 0.6mm, and in the time that the first gap 6 and the second gap 7 are less than 0.6mm, the coupling at 6 places, the first gap and 7 places, the second gap is excessively strong, and loss is larger.In the present embodiment, in the first gap 6 and the second gap 7, be filled with the dielectrics such as plastics, the wherein dielectric constant difference of dielectric, can affect the radiation efficiency of antenna, dielectric constant is less, and loss is less, and the efficiency of gap radiation is higher, the material that can select as the case may be dielectric is not restricted herein.
