Abstract

This invention relates to an inverse-F antenna and its preparation method, in which, the antenna includes a radiation part, an earth part and a connecting part connecting them, the radiation frequency is at the bands of 900MHz and 1800MHz, the processing method includes: 1, selecting a rectangular metal plate, 2, determining the length of the antenna radiation part according to the working bands 900 and 1800MHz of the antenna, 3, determining the height and shape of the connecting part based on the impedance match necessary for the antenna, 4, opening recesses on the metal plate based on said computing result to get a radiation part, a connecting part and an earth part based on the computed result, 5, determining feeding points based on impedance match and providing feed lines electrically connected at the feed points.

Description

[0001] 【Technical field to which the invention belongs】 [0002] The invention relates to an antenna and a manufacturing method thereof, in particular to a planar inverted-F antenna applied to a movable electronic device and a manufacturing method thereof. 【Background technique】 [0003] With the rapid development of modern communication technologies, more and more mobile electronic devices such as notebook computers are equipped with antennas so that they can access a wireless local area network (WLAN) to work. At present, wireless local area networks are mostly based on Bluetooth (Bluetooth) technology standards or IEEE802.11 series standards. The working frequency band of the antenna in the Bluetooth technology standard falls on 2.4GHz, and the working frequency band of the antenna in the IEEE802.11 series technical standards falls on 2.4GHz and 5GHz respectively. Therefore, most of the antennas in notebook computers are antennas applied to the above-mentioned frequency ba...
