Abstract

Microminiaturized type antenna unit includes dielectric material layer, first zigzag line, second zigzag line, and multiple curved lines. Being zigzagged along first direction, first zigzag line is setup on the dielectric material layer. Being zigzagged along second direction, second zigzag line is setup on the dielectric material layer. First zigzag line connects second zigzag line. These curved lines are connected to multiple line breakover points in zigzag lines.

Description

technical field [0001] The present invention relates to an antenna device, and in particular to a miniature antenna device with a single feeding point and multiple meandering lines. Background technique [0002] With the rapid development of the wireless communication industry, various electronic devices, such as mobile phones, computers, networks, etc., now have the function of using wireless communication to achieve signal transmission. The main transmitting and receiving equipment for wireless communication is a signal transceiver and an antenna mounted on it. As electronic devices are becoming lighter, thinner, shorter, and smaller, traditional antennas (such as rod antennas, Yagi antennas, dish antennas, etc.) can no longer meet the needs of the new era. [0003] Therefore, several miniaturized antenna devices have been developed in the prior art. For example: the "built-in vertical dual-frequency antenna" disclosed in Chinese Patent No. 491,417 describes a microstrip...
