Description
Technical field
The utility model relates to coil antenna, particularly NFC (NearFieldCommunication) short-range wireless communication antenna, WPC (WirelessPowerConsortium) wireless charging antenna and PMA (PowerMattersAlliance) wireless charging antenna.
Background technology
NFC (NearFieldCommunication), is called near field communication (NFC), runs in 10 cm distance.Its transmission speed has 106Kbit/ second, 212Kbit/ second or 424Kbit/ second three kinds.Operating frequency is 13.56MHz, is widely used in the field such as wireless payment, transfer of data.Gate inhibition's key, traffic all-purpose card, credit card, Payment Card etc. of airport boarding checking, mansion can be used as.
Wireless charging technology (Wirelesschargingtechnology or Wirelesschargetechnology), also known as doing induction charging, non-contact inductive charging, come from wireless power conveying technology, utilize near field to respond to, namely inductance coupling high, transmitted its energy to the device of electricity consumption by power supply unit (charger), this device uses the energy received to charge to battery, and simultaneously for itself running.Owing to transmitting energy with inductance coupling high between charger and power device, connect without electric wire between the two, the device of therefore charger and electricity consumption can be accomplished to expose without conductive junction point.Its convenience has won the favor of consumer, and the wireless terminal therefore with wireless charging function also more and more enters among market.The wireless charging standard approved in the market is QI (WPC) and PMA.
Inconsistent due to the different of operating frequency and Valuation Standard, cause NFC antenna and wireless charging antenna need take larger area separately, and the designer trends of wireless terminal is light, thin and powerful compatibility.Therefore there is contradiction.Prior art puts together non-overlapping for the wireless charging antenna of NFC and two kind of standard.
Summary of the invention
The purpose of this utility model is the synthesis coil antenna providing the size of a kind of compact conformation, shared substrate little.
The utility model for the technical scheme achieving the above object adopted is: a kind of synthesis coil antenna, comprise substrate and be arranged at NFC coil, PMA Wireless charging coil, the WPC Wireless charging coil on substrate, described NFC coil, PMA Wireless charging coil, WPC Wireless charging coil walk abreast and are arranged on same of substrate, in the space that the coil that PMA wireless charging electric wire and WPC wireless charging electric wire are arranged on NFC coil surrounds, in the space that the coil that WPC Wireless charging coil is arranged on PMA Wireless charging coil surrounds.
Further, the coil cabling of described PMA Wireless charging coil, WPC Wireless charging coil, NFC coil three the same side is parallel to each other.
Further, described substrate is FPC flexible circuit board.
Further, described substrate is arranged three groups of coil terminal pads, i.e. one group of NFC coil terminal pad, one group of PMA Wireless charging coil terminal pad and one group of WPC Wireless charging coil terminal pad, three groups of coil terminal pads be arranged on substrate with coil the same face, the two ends of NFC antenna coil, PMA Wireless charging coil and WPC Wireless charging coil are connected on corresponding coil terminal pad respectively by via hole and back side copper clad layers.
Further, described three groups of coil terminal pads, namely one group of NFC coil terminal pad, one group of PMA Wireless charging coil terminal pad and one group of WPC Wireless charging coil terminal pad, be arranged on the golden finger position of substrate.
Further, what the interval between described NFC coil, PMA Wireless charging coil, WPC Wireless charging coil three adjacent windings was greater than adjacent windings walks distance between centers of tracks.
The size of the substrate shared by the utility model is little, simultaneously two various criterions of compatible wireless charging.
Accompanying drawing explanation
Fig. 1 is the schematic diagram of the utility model preferred embodiment.
Embodiment
Below in conjunction with drawings and Examples, the utility model is described in further detail:
As shown in Figure 1, a kind of synthesis coil antenna, the NFC coil 1, PMA Wireless charging coil 2, the WPC Wireless charging coil 3 that comprise substrate 4 and be arranged on substrate 4, described NFC coil 1, PMA Wireless charging coil 2, WPC Wireless charging coil 3 walk abreast and are arranged on same of substrate 4, in the space that the coil that PMA Wireless charging coil 2 and WPC Wireless charging coil 3 are arranged on NFC coil 1 surrounds, in the space that the coil that WPC Wireless charging coil 3 is arranged on PMA Wireless charging coil 2 surrounds.
The operating frequency that the utility model utilizes NFC antenna different separately with wireless charging antenna and different dimensional requirements, PMA Wireless charging coil 2 and WPC Wireless charging coil 3 are arranged in the coil space of NFC coil 1, make three antenna synthesis on the same face of same substrate, thus reduce the volume of whole antenna, and realize different functions.
The coil cabling of described PMA Wireless charging coil 2, WPC Wireless charging coil 3, NFC coil 1 three the same side is parallel to each other.Can very easily PMA Wireless charging coil 2, WPC Wireless charging coil 3, NFC coil 1 be separated with other roads on substrate 4, thus save more terminal inner space, complete compatible design.
Described substrate 4 is FPC flexible circuit board.Because other circuit may be provided with on FPC flexible circuit board, in order to improve the space availability ratio of substrate 4.
Conveniently NFC antenna is connected with related circuit with wireless charging antenna, described substrate 4 is arranged three groups of coil terminal pads, i.e. one group of NFC coil terminal pad, 5, one group of PMA Wireless charging coil terminal pad 7 and one group of WPC Wireless charging coil terminal pad 6, three groups of coil terminal pads are arranged on one side same with coil on substrate 4, and the two ends of NFC antenna coil 1, PMA Wireless charging coil 2 and WPC Wireless charging coil 3 are connected on corresponding coil terminal pad respectively by via hole and back side copper clad layers.Described three groups of coil terminal pads, i.e. one group of NFC coil terminal pad, 5, one group of PMA Wireless charging coil terminal pad 7 and one group of WPC Wireless charging coil terminal pad 6, be arranged on the golden finger position (substrate edges protrudes in finger-shaped place) of substrate 4.Therefore, NFC coil terminal pad 5, PMA Wireless charging coil terminal pad 7 and WPC Wireless charging coil terminal pad 6 are all arranged at outside NFC coil 1, thus are conveniently connected with related circuit.
Mutually disturb to weaken between coil, what the interval between described NFC coil 1, PMA Wireless charging coil 2, WPC Wireless charging coil 3 three adjacent windings was greater than adjacent windings walks distance between centers of tracks.The interval of a segment distance must be had between NFC coil 1 and PMA Wireless charging coil 2, WPC Wireless charging coil 3, thus reduce the mutual interference between NFC antenna and wireless charging antenna, improve antenna stabilization performance.
The NFC antenna that the utility model provides and wireless charging antenna, by the synthesis of three aerial coils, namely meet demand compatible between different authentication standard, can reduce again the inner space of Terminal Design simultaneously, thus reach cost-effective object.
