Abstract

The invention provides a miniaturized dual-band antenna, which comprises a first dipole arm and a second dipole arm which are symmetrical to each other, and a dipole formed by the first dipole arm and the second dipole arm is used for generating a first resonance point; the first dipole arm and the second dipole arm are respectively provided with a first U-shaped groove, the two first U-shaped grooves are mutually symmetrical, openings of the two first U-shaped grooves are opposite, the first U-shaped grooves are used for generating a second resonance point, and the frequency of the first resonance point is different from that of the second resonance point; the two ends, close to each other, of the first dipole arm and the second dipole arm are connected with the feed structure. According to the dual-frequency antenna, a novel dual-frequency structure is adopted, a plurality of slot combinations can be loaded to realize broadband matching at a high frequency band, meanwhile, the dual-frequency antenna has the advantages of miniaturization and high radiation efficiency, and the requirement of a Wifi 6E frequency band can be well met.
