Embodiment Construction

[0024] Please refer to figure 1 As shown, the tri-band dipole antenna 1 of the present invention includes a dipole antenna 20 , an insulating substrate 30 and a feeder 40 .

[0025] The dipole antenna 20 is a thin metal sheet attached to one side surface of the insulating substrate 30, which is roughly in the shape of a longitudinal strip and includes a first radiating portion 24, a second radiating portion 22, a first grounding portion 23, and a second grounding portion. twenty one. The first radiating portion 24 and the second radiating portion 22 are symmetrically disposed on the insulating substrate 30 with the first grounding portion 23 and the second grounding portion 21 . Wherein the second radiating part 22 works in a lower frequency band, and it is an elongated structure with a wider end and a narrower end, and the narrower end is disposed in the middle of the insulating substrate 30 . The first radiating part 24 works in a higher frequency band. It is an elongated ...

Abstract

The present invention relates to a three-frequency doublet antenna and its making method. Said three-frequency doublet antenna includes insulating base plate, doublet antenna and feeder line, the doublet antenna includes symmetrically arranged radiation portion and grounding portion, in which the radiation portion and grounding portion are equipped with L-shaped open groove respectively. Said correspondent making method includes the following steps: providing an insulating base plate, symmetrically placing two identical metal thin sheets on the surface of the insulating base plate, respectively cutting L-shaped open groove on every metal thin sheet, dividing every metal sheet into two portions which have a common end and are different in area, providing a coaxial feeder line and making its metal braided layer and inner core conducting wire respectively be electrically connected with two metal thin sheets.

Description

【Technical field】 [0001] The invention relates to an antenna and a manufacturing method thereof, in particular to a three-frequency dipole antenna installed in an electronic device for receiving or transmitting signals and a manufacturing method thereof. 【Background technique】 [0002] At present, as one of the fastest-growing wireless communication technologies, wireless local area network (WLAN) mainly adopts the four major standards of IEEE802.11g, IEEE802.11b / a and Bluetooth, among which the standards of IEEE802.11g, IEEE802.11b and Bluetooth are applicable to 2.4 GHz frequency band, while another standard IEEE802.11a is applicable to the 5GHz frequency band. [0003] In the previous development, the standard based on 2.4GHz was widely used. Now with the further development of wireless network, IEEE802.11a can also provide the transmission speed higher than any other WLAN solution for the entire coverage area, and the use of frequency band Many advantages, such as not b...
