Figure-Figure 'shows the first habitual PIFA antenna structure. The antenna (for receiving and transmitting two different frequencies of electromagnetic waves, uses the feed pin (丄 丄) to feed current into the radiating element (1 2) When the current is divided into two paths, the electromagnetic waves of different frequencies are emitted due to the difference in the length of the two paths. Because the length of the radiating element (丄 2) is determined by its predetermined operating frequency, which is generally 1/4 of the operating wavelength, the stomach The antenna (1 0) is used to divide the radiating element (丄 2) into the left and right paths. The combined antenna length will not meet the requirements of miniaturization of the antenna size, and the feed pins (1 i) of the conventional antenna are located in two Between the radiating elements (1 2) at the working frequency, when the distance between the feed pin (1 1) and the ground pin (丄 3) needs to be adjusted for proper impedance matching, it will also affect the radiating element (丄 2) The characteristics of the 5 M282338 signal send and receive, so that the impedance matching of conventional antennas is not easy to adjust. [New content] The main purpose of this creation is to provide a dual-frequency antenna structure, which uses the special composition of the radiating part. Make antenna It is easy to miniaturize, and it can simplify the structure of the radiating part, and then meet the needs of economic cost and miniaturization of electronic equipment. The secondary purpose of this creation is to use the special composition of the radiating part and the feeding end to make the antenna easier to block. Adjuster who resists and matches. [Implementation method] In order to allow your review committee to have a better understanding and understanding of the purpose, characteristics and effects of this creation, please cooperate with [Simplified Illustration of the Schematic] as detailed below: Please cooperate Refer to Figures 1, 2, and 3, 'This creation provides a dual-band antenna structure, which includes: a ground portion (20), a connection portion (30), and a top connected to the connection portion (30). The radiating part (40) and the feeding end (5Q) opposite to the grounding part (20) are formed by the electrical connection between the coaxial feeding line (60) and the grounding part (20), where the connection The lower end of the part (30) is connected to the ground part (20) ❸-side, which is characterized in that the upper end of the connection part (30) is connected by a turn-an arm (7Q) of an appropriate length and is connected to the ground part (20). ) Opposite so that the end of the arm (70) is connected to the feed end (5 Q) Zhi-side 'The detail (4〇) is connected by the other side of the feeding end (5 Q)-the -th arm of appropriate length (4 Q 1) and the reverse direction from the __arm (4 Q 丄) Extend a long and adjacent second radiating arm (402) that is adjacent to the support arm (70). This creation is a kind of dual-frequency antenna structure, in which the second radiating arm (402) At the free end, M282338 can also form a folded edge (4 Ο 3) [Effect description] 1. This creation uses the first jurisdiction to shoot the arm (divide the -㈣ 博 (4 〇 丨)) to construct a connection to the second The radiating arm (4 Q 2), in addition to the two radiating arms (4 〇 2) can be used as the first-working frequency, and also has a connection to the first frequency, which can shorten the conventional ㈣1 to make the second Korean shooting arm (4 G 2 ) Can be used as the second work one or two light shooting arms (4 Q i) (the length of the antenna is increased by the left and right _ component configuration, and in the first state, only 1㈣ 4 Q 2) is needed to connect Or the metal material used as the antenna for the antenna, as a whole) is used as a connector, so it can greatly reduce the production efficiency. Q — 1 The size of the antenna is reduced and the manufacturing cost is reduced. 2 . The feeding end (5Q) of this creation is located at the _then surface -4 ^ (4 0 1) and the support arm (7 0) 'in ::: arm (4 ° 1) (4 ° 2) The overlap area is reduced to the minimum, so ㈡ (6 —_ (2q)), which is matched with the connection part and adjusted with the mesh position, can “easily adjust the input impedance matching of the dual-frequency antenna, and Those who will affect the light emitting part (40) 〇, lice and radiation receiving and transmitting effects. 3 · In this work, the two thin arms (4 Q 2) are also purely "minded and formed-the folded edge (4 0 3), so that the plane length required for a round shot (4 Q 2) is reduced by- However, the overall length still meets the turning point of the size 3 required by the operating frequency and shrinks to meet the space requirements of miniaturized electronic equipment. Σ This can also reduce the size of the antenna, 4 · This creation of the second radiating arm (4 〇2) The folded edge (η η, υ d) 'can also be formed into a linear configuration with the second radiating arm (4 ◦ 2).
