Abstract

The invention discloses a multi-band miniaturized planar monopole antenna which comprises a medium substrate, a first antenna radiation unit, a second antenna radiation unit, a micro-strip feeding line and a ground plate, wherein the first antenna radiation unit, the second antenna radiation unit, the micro-strip feeding line and the ground plate are made of copper material, and copper is applied to the surface of the medium substrate by using a laser technology or a corrosion technology. According to the multi-band miniaturized planar monopole antenna, only two radiation units are used, three bands are achieved, and the antenna is simple in structure, has no via hole and is easy to process and mold and low in cost. Miniaturization of the antenna is realized by using a circuitous flow method of the circuitous radiation units. The antenna of the invention adopts a feeding method combining direct feeding and coupled feeding, thus effectively improving impedance matching of the antenna. The antenna of the invention is suitable for a plurality of wireless communication frequency bands.

Description

technical field [0001] The invention relates to an antenna suitable for a mobile terminal in a wireless communication system, in particular to a multi-band miniaturized planar monopole antenna, which belongs to the technical field of monopole antennas. Background technique [0002] With the continuous development of communication technology, mobile terminals are developing in the direction of multi-function and miniaturization. In addition to basic communication functions, mobile terminals also require functions such as Wi-Fi wireless interconnection, Bluetooth wireless data transmission, RFID radio frequency identification, and 4G high-quality video image transmission. The wireless electromagnetic wave frequency bands used to realize these functions are different, and the mobile terminal needs to work in the corresponding wireless electromagnetic wave frequency band to realize the corresponding functions. Therefore, the antenna serving as the electromagnetic window of the ...
