New description: [New technical field] This creation refers to a kind of planar multi-frequency dipole antenna structure, which is close to the configuration of the starting end of the thin conductor and the grounding conductor and a continuous meandering design. The coaxial feeder and the antenna are electrically connected more easily, and the overall size of the antenna can be greatly reduced. _ [Prior Art] Press, in the communication module, the key components of the antenna signal transmission and reception, as for the conventional planar dipole antenna, please refer to Figures 5 and 6, the antenna includes: (1), a grounding portion (2), an insulating substrate (3), and a coaxial cable (4), wherein the radiating portion (1) and the grounding portion (2) are respectively disposed on both sides of the insulating substrate (3), in the radiating portion (1) a first feeding point (5) is provided, the grounding portion (2) is provided with a second feeding point (6), an inner core (7) of the coaxial cable (4), and a braid conductor (8) ) is respectively connected to the first feed point ～(5) and the first feed point (6) for feeding the signal, due to the first feed point (5) of the radiating portion (1) and the ground portion (2) The second feeding points (6) are arranged side by side at the left and right intervals. When the coaxial cable (4) has to be taken out from the lower side of the insulating substrate (3), the braided conductor (8) of the same cable (4) can be Easily soldered to the first feed point (6) of the grounding section (2), but the inner core (7) of the coaxial cable (4) is not directly connected to the first feed point (5) of the radiating section (1) Alignment welding Because the inner core (7), and the complex direction are different from the first feed point (5), it is necessary to increase the process and firstly bend the inner core (7) to the first feed point (5). It is only possible to weld the inner core (7) with the first feed 5 M296492 point (5), thereby causing troubles in the welding operation of the ridge shaft cable (4) and the antenna, and when the dipole antenna is used in multiple frequency implementation, The extension of the size of the emitter and ground terminals due to the requirements of the specific satellite frequency band has also contributed to the inability of the planar dipole antenna to meet the needs of today's miniaturized, flexible and flexible electronic devices. In view of this, the creator has been engaged in the manufacturing development and design experience of related products for many years, and after the design and careful evaluation of the above objectives, he has finally obtained the practical creation. [New content] The main purpose of this creation is to provide a multi-frequency dipole antenna structure with a ten-sided diameter, which makes the electrical connection between the coaxial feeder and the antenna easier.
