Description

Antenna structure

Technical field

The utility model relates to a kind of antenna structure, particularly relates to a kind of antenna structure that is sticked in other assembly.

Background technology

In recent years, because the convenience of wireless telecommunications has brought up the flourish of wireless telecommunications industries, especially wireless phone is universal, has almost become the necessity of modern's life.In short several years, use the lasting growth of population of mobile phone, and the demand of whole world mobile phone will reach more than 500,000,000 every year.Antenna in the device of wireless telecommunications is to transmit and receive the data of wireless system at the wireless telecommunications role.Along with flourish and various communication product of wireless telecommunications all is tending towards miniaturization, in order to meet this demand, some embedded antennas also want cube little, and plate aerial is except meeting the antenna body complanation with the purpose that reaches miniaturization, geometry external form if can effectively changing on the Antenna Design on the flat board will have more multifarious Antenna Design.And such Antenna Design is quite general in supporting the embedded mobile communication device of antenna of multifrequency, in addition its near isotropic radiation characteristic also be used to the mobile communication device antenna reason one.

Seeing also Fig. 1, is the schematic diagram for known technology middle plateform antenna.Among the figure, plate aerial includes a substrate 11, a radiation metal 12, a feed side 13 and an earth terminal 14, and wherein, this plate aerial is only for receiving and the wireless signal of launching single frequency band.Therefore, after the improvement via the research staff, with this type of plate aerial as shown in Figure 2, be the schematic diagram that shows dual frequency flat panel antenna in the known technology.And, Fig. 2 middle plateform antenna package contains a substrate 21, two radiation metal 22 and 23, a feed side 24 and earth terminals 25, wherein, two radiation metal 22 and 23 are shared identical feed side 24 and earth terminals 25, but have the wireless signal of different length in order to the transmitting-receiving different frequency bands, long radiation metal 22 is in order to transmitting-receiving low frequency wireless signal, and short radiation metal 23 is in order to the transmitting-receiving high-frequency wireless signals.Yet, the radiation metal of above-mentioned two class plate aerials, feed side and earth terminal are with kinds of processes technology such as electroplating, inlay these unit to be arranged on the substrate, so will cause the increase of cost, and when installing above-mentioned plate aerial in circuit board, need vacate a separate space is installed, thereby cause unnecessary space and cost waste, and become the restriction of communication device miniaturization.

For satisfying the above-mentioned communication device miniaturization that proposes, the demand that need reduce the communication device space as far as possible.The utility model people integrates The Research of Relevant Technology and the many practical experience of Related product development and maintenance based on being engaged in communication system for many years, inquire into through research and design in many ways and special topic, satisfy in the utility model proposes a kind of antenna structure with as aforementioned expectation one implementation and foundation.

Summary of the invention

The purpose of this utility model is to provide a kind of antenna structure, and a kind of antenna structure that is sticked in other assembly particularly is provided

Edge is, for reaching above-mentioned purpose, according to antenna structure of the present utility model, it is to include a radiation sheet metal and have a feed side and an earth terminal, simultaneously, form a hole in radiation sheet metal, this hole has the edge that a breach and breach extend to radiation sheet metal.

From the above, because of according to antenna structure of the present utility model, borrow its hole with on the assembly that is sticked in portable communication device, as the design of saving the portable communication device inner space.
