Abstract

A multi-band plannar antenna has 3 radiation units, which are working at different 3 bands and combined to form a plane. Said radiation unit is prepared by printing conductor and / or circuit on a multi-layer dielectric substrate.

Description

technical field [0001] The present invention relates to a multi-band planar antenna, in particular to a method in which conductor lines are respectively printed on the surface of a dielectric material (dielectric material) base material, and each layer of conductor lines is connected by means of electrical connection such as perforation and electroplating to form a multi-band antenna. Three-dimensional meandering type planar antenna. It can be used in radio receiving and transmitting antennas of various wireless communication devices, such as: wireless mobile phone (Wireless Mobile Phone), wireless modem (Wireless Modem), wireless local area network (LAN). Background technique [0002] Due to the rapid development of the wireless communication industry, all kinds of communication products and technologies are constantly introducing new ones, and the competition is fierce; communication products not only emphasize multi-function, variety, lightness and shortness; this require...
