Creation Instructions (l)-[Technical Field to which the New Type belongs] This creation is about an antenna structure, especially an antenna structure suitable for two frequency bands. [Previous technology] Antenna waves are used to transmit the operating wavelength plus, the world's communication equipment may be installed suitable for carrying, including a variety of methods, although including a lot of ', and for the frequency or multi-frequency this requires a [new type is wireless information, related Many countries can set up multiple antennaless elements at the same time, which can eliminate the need for long antenna cables to provide long-term elimination of antennas.] Telecommunications systems and antennas In recent years, the standards adopted for antennas are more suitable for wireless communication equipment. There are multiple components, each of which is more difficult to use. The front end of the multi-function system has a wide range of types. Individual movement is inaccurate and the frequency band is different from the same frequency range. In addition, the antenna elements can be shortcomings of the antenna. The antenna structure is shortened. To achieve this purpose, the key is to apply to dual-band antennas. It is the same as the line transmission of the antenna, and it is applied on the first line. However, some people have suggested that it is applicable, but it must be more quickly added to the design and equipment of the antenna. This method of making wireless wireless communication equipment does not originate from a specific frequency band in an antenna. Therefore, the antenna inside this antenna is complex with wireless communication services. The $ key component is the j-line structure.

Creation Instructions (2) A coaxial transmission line is connected in series to the other end of this second metal body. In this work, the antenna can operate in two frequency bands at the same time by the capacitive and inductive effects generated by two metal bodies. In the following, detailed descriptions are given with specific examples and accompanying drawings to make it easier to understand the purpose, technical content, characteristics and achieved effects of this creation. [Embodiment] In order to allow an antenna structure to operate more than one at the same time Different frequency bands, this creation proposes to add a metal body to a conventional single-frequency dipole antenna so that the antenna can operate in two frequency bands. The dual-frequency antenna of this creation is shown in the first figure, which includes a first The metal body 10 is connected in series with a second metal body 12, wherein the first metal body 10 and the second metal body 12 are usually copper tubes, and the second metal body 12 is connected in series with a coaxial transmission line. In order to protect the internal components of the antenna, a set of shells 16 is usually sleeved on the periphery of the first metal body 10, the second metal body 12, and part of the coaxial transmission line 14. The information to be transmitted is transmitted to the antenna through the coaxial transmission line 14 ', and the information is radiated by the first metal body 10 and the second metal body 12, and the first metal body 10 and the second metal body 12 receive the information. The information is also transmitted by the coaxial transmission line 14 to the receiver system. The structure of a general single-frequency dipole antenna is shown in the second figure, which includes an antenna conductor 20, a coaxial transmission line 22, and a metal invitation 24 for covering a portion of the coaxial transmission line.
