Abstract

The invention discloses a directional dual-frequency antenna. The directional dual-frequency antenna comprises an irradiator, a microstrip Balun, a first transmission line, a second transmission line and a reflective plate, wherein the irradiator is provided with a groove, a gap and a bent part, the inner end of the gap is connected with the groove, the outer end of the gap is opened, a first edge of the bent part is connected with a first edge of the gap, and a second edge of the bent part is connected with a second edge of the gap; a first end of the first transmission line is connected with the irradiator, a second end of the first transmission line is connected with the microstrip Balun, and a first end of the second transmission line is connected with the irradiator; and the reflective plate is arranged below the irradiator, separated from the irradiator and connected with the microstrip Balun. According to the embodiment of the invention, the directional dual-frequency antenna has the advantages of ultra wide band, high gain, high front-to-back ratio, high axial cross polarization ratio, good consistency in directional diagram, small volume, simple structure, low manufacturing cost and the like, and is convenient to process.

Description

technical field [0001] The present invention relates to the communication field, in particular to a directional dual-frequency antenna. Background technique [0002] The wifi antenna is an indispensable part in the wifi communication link. Currently, existing wifi antennas include single-band antennas and dual-band antennas (such as Yagi antennas). However, dual-band antennas can only work within a narrow bandwidth. Moreover, different countries and regions set up different 5G frequency bands, resulting in different wifi communication channels used in different countries and regions, and the working frequency bands of wifi antennas are also different, which increases the cost for manufacturers in design, manufacturing and other links. Contents of the invention [0003] The present invention aims to solve one of the technical problems in the related art at least to a certain extent. For this reason, the present invention proposes a directional dual-frequency antenna with...
