New description: [New technical field] [0001] This creation relates to an RFID electronic tag, especially a panel antenna with RFID electronic tag function. [Prior Art] [0002] RFID electronic tags are widely used in the field of logistics. It can store the relevant data of goods, credit cards or access control cards in the RFID chip. After being read by the RFID reader, it can carry out commodity checkout, commodity inventory management, credit card swipe and identification. [0003] At present, the RFID electronic tag used in the market is prepared with a plastic sheet, a receiving and transmitting antenna is formed on the plastic sheet, and an RFID chip is pasted on the plastic sheet, and the RFID chip is connected. The foot is electrically connected to the antenna. When the RFID electronic tag is completed, the surface of the antenna and the RFID chip are directly coated with adhesive so that the RFID electronic tag can be attached to the product. [0004] Since the traditional typical RF ID electronic tag application is limited by environmental factors, interference and diffraction are easily formed in water, liquid or high humidity air, or the metal surface may cause high error rate of data reading. . [New Content] [0005] The main purpose of this creation is to improve the lack of traditional RFID electronic tags. This creation combines RFID chips and RFID antennas of RFID tags. Since the area of the grounding layer of the panel antenna is larger, and the receiving effect of the panel antenna is better, the panel antenna with the RFID electronic label can be applied to the metal sheet or the metal sheet having a larger area or liquid. Page 3 of 20 M397611 - On November 16, 099, on the replacement page, the RFID reader will not be disturbed when reading data. [0006] In order to achieve the above object, the present invention provides an RFID electronic tag type panel antenna, comprising: [0007] a substrate, which is a ceramic material having a front surface and a back surface; [0008] a metal radiation layer, And a metal radiation layer having an area equal to or smaller than an area of the front surface of the substrate, and having at least one first electrode portion on one side of the metal radiation layer; [0009] a metal ground layer is disposed on a back surface of the substrate, the area of the metal ground layer is equal to an area of the back surface of the substrate or smaller than an area of the back surface of the substrate, and one side of the metal ground layer has at least one second electrode portion. The second electrode portion extends on the front side of the substrate; [0010] an RFID chip is disposed on the front surface of the substrate, the RFID chip has a plurality of pins on both sides thereof, the pin is coupled to the first electrode portion and the first electrode portion The two electrode portions are electrically connected. [Embodiment] [0011] The detailed description and technical content of this creation are as follows: ' [0012] Please refer to the first, second and third figures for the decomposition of the panel antenna and RFID chip of this creation. And a combination of the appearance and the rear view of the panel antenna. As shown in the figure: The RFID electronic tag type panel antenna 10 of the present invention comprises: a substrate 1, a metal radiant layer 2, a metal ground layer 3 and an RFID chip 4. [0013] The substrate 1 is made of a ceramic material and has a square or rectangular body having a front surface 11 and a back surface 12. Form No. A0101 Page 4 / Total 20 pages November 16th, 2010, the replacement page [00M] The metal radiation layer 2 is disposed on the front surface of the substrate 1, and the metal radiation layer 2 is used for receiving Transmitting a signal, and the metal radiation layer 2 has a distribution area equal to an area of the front surface U of the substrate 1 or an area smaller than the front surface n of the substrate, and has at least one first electrode portion (microstrip) on one side of the metal core layer 2 Line) 21. [0015] The metal ground layer 3 is disposed on the back surface 12 of the substrate 1. The metal ground layer 3 is used for grounding, and the metal ground layer 3 has a distribution area equal to or smaller than the area of the back surface 12 of the substrate 1. The area of the back surface 12 has at least one second electrode portion 31 on one side of the metal ground layer 3, and the second electrode portion 31 extends over the front surface π of the substrate 1. [0016] The RFID chip 4 is conventionally disposed on the front surface 11 of the substrate 1. The RFID chip 4 has a plurality of pins 41 on both sides thereof, and the pins 41 are connected to the first electrode portion 21 and the first electrode portion The two electrode portions 31 are electrically connected. The RF丨D chip can receive the signal transmitted by the external RFID reader (not shown) through the metal radiation layer 2, and transmit the signal of the RFID chip 4 to the rf ID reader. [00丨7] Please refer to The fourth and fifth figures are schematic cross-sectional views of the flat antenna of the present creation and the fourth figure at the position of 5-5. As shown in the figure, it can be clearly seen from the drawing that the front surface 11 of the substrate 1 has a metal radiation layer 2, and the back surface 12 of the substrate 1 has a metal ground layer 3, and the first electrode portion 21 of the metal radiation layer 2 is The RFID wafer 4 is electrically connected between the second electrode portions 31 of the metal ground layer 3. Since the RFID chip 4 is disposed on the planar antenna 1 ,, the larger the area of the metal ground layer 3 of the panel antenna 10 is, the better the receiving and transmitting effect of the planar antenna 1 ' is, so that the RFID electronic tag can be used in the volume. Large metal object products (not shown), and receive and form number A0101 page 5 / 20 pages of the signal on November 16, 099 will not be disturbed, different from the traditional evaluation. Electronic tags cannot be used on products with large metal objects. [0018] For example, referring to the sixth figure, the present invention installs the (10)...electronic tag type panel antenna 10 on the metal license plate 2 of the vehicle, the metal ground layer 3 of the back surface 12 of the substrate 1 and the metal of the vehicle. After the license plate 2 is in contact, the grounding area is increased, so that the receiving and transmitting effects of the panel antenna 10 are better, and when transmitting and receiving signals, the external RFID reader 30 is not interfered by the large metal object. The data stored in the RFID chip can be read. [0019] Please refer to the seventh and eighth figures, which are schematic cross-sectional views of another embodiment of the present invention and a seventh figure. As shown in the figure: After the creation of the "D-electronic tag type flat panel antenna", the created flat panel antenna 1 can be mounted in a plastic case 5. The housing 5 includes: The base 5i, a backing rubber 52, an upper cover 53 and a waterproof and breathable film 54. The base 51 has an accommodating space 511 for accommodating the flat antenna 1 ,, and the accommodating space 511 has a groove at the periphery thereof. The groove 51 2 is used for assembling the upper cover 53. When the upper cover 53 is assembled, a waterproof strip or glue can be placed in the groove 512. When the upper cover 53 is assembled to the groove 512, The waterproofing effect is provided on the base 51 and on the two sides of the accommodating space 511. The set of connecting holes 513 is for the base 51 to be locked or fixed to the metal object. Or the double-sided adhesive is attached to the back of the base 51 and directly adhered to the article. [0021] The adhesive 52 is a double-sided adhesive or a glue, and the flat antenna 10 is adhered to the receiving space. [0022] The upper cover 53 is assembled in the groove 512 and has an outer surface form number A0101 thereon. 6 pages / total 20 pages November 16th, 2010, according to the replacement page 531 and an inner surface 532, the outer surface 531 has a venting hole 53 3 through the upper cover 53. [0023] the waterproof breathable film 54, The inner surface 532 of the upper cover 53 is attached to the inner surface 532 of the upper cover 53 and the venting hole 533 is sealed. The waterproof gas permeable film 54 prevents the external moisture from entering the accommodating space 511, and the gas or moisture inside the space 511 can be accommodated. After the waterproof permeable film 54 is discharged, the accommodating space 511 is kept in a dry state.
