More recently ... the door trend, if a new product In order to gain widespread acceptance and affirmation in the market, the appearance, size, and performance of its products are often the key. φ-Dual-frequency antenna design generally applicable to wireless communication products. Conventional antennas can be roughly divided into two types. The first type is an inverted-F flat antenna; the second type is a y-dipole antenna. The above-mentioned operating core of the 1 / 4-wavelength resonance of _____________, but because the bandwidth of the inverted F-shaped flat-panel antenna is small, it is often limited; on the other hand, the single-dipole antenna has a larger operating frequency. However, the design of the conventional antenna has the disadvantage that the height of the antenna is too far from the ground plane (which is the longest in the record). This creates restrictions on the appearance of the product and is not suitable for mobile communication phones. The purpose of this month is to provide a wheel-emitting metal sheet suitable for a planar single dipole antenna. The light-emitting metal sheet has a reduced area and the basin width is less than 2% of the minimum operating wavelength. , The entry point and at least-the slit; the at least-slit extends from one edge of the radiating metal sheet to the inside of the light-emitting metal sheet, so that the light-emitting metal sheet forms a single path, where the path is in consideration of the dual frequency The current path of the two dipole frequencies of a single dipole antenna, where the two operating frequencies include-a high frequency and a low frequency, the length of the path is close to 1/2 of the high frequency, and the length of the path is close to the low 1/4 wavelength. Therefore, you can get a job with this and gold injection. 作 作 的 发 日本 · has a relatively low width 518804 A7 B7 Printed by the Consumer Cooperatives of the Central Standards Bureau of the Ministry of Economic Affairs 5. Description of the invention (2) Another object of the invention It is to provide a dual-frequency planar single dipole antenna; the radiating metal sheet and its feeding metal wire form an angle of about 90 degrees, that is, the radiating metal sheet and the product ground plane are arranged in a vertical or near vertical manner, here In this configuration, the maximum height of the antenna from the ground plane of the product can also be less than 2% of the minimum operating wavelength. At this time, when the antenna is applied to a wireless communication mobile phone, it is very suitable for placement or concealment in the mobile phone casing. Referring to FIG. 1, the dual-frequency planar single dipole antenna and the radiating metal sheet of the present invention include a radiating metal sheet u, a dielectric substrate 12, a feed point or a surface-attached solder joint 13, and a signal transmission line 14 , A ground plane 15, a dielectric substrate 16 and a feed-in metal wire 17. The ground plane 15 is used to electrically ground the substrate. The material of the substrate 12 is a microwave substrate, which is used for printing or money engraving. The metal sheet feeds the metal wires. It can be printed or money engraved on the dielectric substrate π (its typical size is 100 X 35). mm2, which can be regarded as a circuit board of a mobile communication mobile phone) 'Used to connect the transmission line of E and the radiating metal sheet to convey the signal —' The angle 18 between the feeding metal line and the light-emitting metal sheet is about 90 degrees. I FIG. 2 is an embodiment of the radiating metal sheet of the present invention. The radiating metal sheet 2 includes: a feed point or a surface-attached solder joint 22 and a slit ^ = the input point 22 is connected to the feed metal wire. 17; The slit 23 is made of the radiant gold. The edge of the sheet extends to the inside of the radiating metal sheet, and the area of the slit: forms a single-shaped meandering radiating metal wheel 21, and the meandering metal sheet has a -starting end and -end, and the feeding point is located at The beginning 1 is near, the end extends to the inside of the radiant metal sheet and is covered by the path, attached with paper size suitable for the family _ home standard mm) (please read the precautions on the back before filling this page) installation line 518804 A7 __B7 V. Explanation of the invention (3) Since the radiating metal sheet of the present invention uses only a single meandering metal sheet path to achieve dual-frequency operation, the antenna area of the present invention can be reduced accordingly, and the current thin and short practical requirements are achieved. Figure 3 is the measurement result of the return loss experiment of this embodiment. The visibility of the radiating metal sheet is only 5 mm and the length is 27 mm. At the same time, the length of the feeding metal wire is only 5 colors. At this time, the overall height of the antenna is The ground plane is only about 5 planes (less than 2% of the operating wavelength of 900 MHz); it can also be seen from the results that the antenna of the present invention successfully excites two modalities around 900 and 1850 MHz, which is sufficient to cover the mobile communication system GSM (890-960 MHz), DCS (17HM880 MHz) and PCS (1850-1990 MHz). Fig. 4 is another embodiment of the radiating metal sheet of the present invention. The radiating metal sheet 4 includes a feed point or a surface-adhered solder joint 42 and a slit ridge. The feeding point 42 is connected to the feeding metal line, and the slit M—the edge of the light-emitting metal sheet extends to the inside of the radiating metal sheet, and is separated by the slit to form a single- The radiation gold is 41, and the miscellaneous end (with a feeding point) of the radiant metal sheet is thinner and the end is thicker and wider, so-to effectively increase the excitation current at the end of the radiant metal sheet / Size, the sky and radiation efficiency will be improved, the equivalent surface current path will also increase, and the area of the radiating metal sheet will decrease due to the increase of the equivalent surface current path, making the county ’s solar limb line The area can thus be reduced.
