Description

Antenna technology field

The present invention relates to a wireless fidelity (WIFI)/Bluetooth (BT)/Global Positioning System (GPS) antenna technology, and more particularly to an antenna. Background technique

With the enhancement of the functions of smart phones, it is necessary to coexist with multiple antennas under the premise of collecting a large number of hardware functions. Therefore, in the design, it is necessary to consider the implementation of the antenna scheme and its regional selection.

In general, functional antennas include: main antenna, WIFI/BT antenna, GPS antenna, China Mobile Multimedia Broadcasting (CMMB) antenna, FM (Frequency Modulation) antenna, Near Field Communication (NFC, Near Field Communication antenna. The main antenna includes Long Term Evolution (LTE), Longband Evolution (WCDMA), Wideband Code Division Multiple Access (WCDMA), Time Division (TD, Time Division), and Synchronous Code Division Multiple Access (SCDMA, Synchronous). Code Division Multiple Access) / Code Division Multiple Access (CDMA).

From the current general needs, WIFI/BT/GPS antennas are already a mandatory feature in peripheral functions, and the design of WIFI/BT/GPS antennas requires a new solution based on the following three reasons:

(1) The demand for diversity antennas in 3G/4G communication leads to a reduction in the layout point of WIFI/BT/GPS antennas;

(2) In the hardware layout and ID design layout, the space reserved for the antenna is getting smaller and smaller; (3) Limited implementation space in the presence of multiple antennas.

Figure 1 shows the layout of a conventional mobile phone antenna. As shown in Figure 1, in the existing Smart Phone antenna design, area 1 is usually used for the main antenna, and the distribution of other antennas except the main antenna is: Area 2 And area 3 is used for GPS antenna, WIFI/BT antenna or diversity antenna, and area 4 and area 5 are used for WIFI/BT antenna, NFC antenna. The antenna layout shown in Figure 1 is a conventional design in an ideal state.

At present, the WIFI/BT/GPS antenna is realized by stainless steel or flexible printed circuit board (FPC), and the antenna is restricted by the structure and layout space. When encountering the design and layout of the large battery ID (InDesign), Due to the limitation of structure or circuit layout, the antenna loses the clearance area, and the current miniaturization and ultra-thinning trend of the intelligent terminal makes the antenna height too low. In the case of loss of headroom, the antenna implementation usually uses the form of Planar Inverted-F Antenna (PIFA), but the PIFA antenna requires a high degree of support. In this way, a missing highly supported PIFA program does not meet the normal target requirements. It can be seen that the environment of Area 2, Area 3, Area 4, and Area 5 is not conducive to antenna design. In addition, in the design of the ultra-thin machine, the WIFI/BT/GPS antenna is inefficient due to the inability to meet the relative headroom. Summary of the invention
