Abstract
A horizontally polarized omnidirectional multi-band antenna structure includes a substrate and two structurally-symmetric radiators, each being provided on a layout area on one of the two opposite sides of the substrate, and including a X-shaped primary microstrip line, four secondary microstrip lines, four primary stubs, four secondary stubs and four resonators. The primary microstrip line has four end points arranged with the secondary microstrip lines along different extending directions. The primary stubs extend along different directions from four sections of the primary microstrip line. Each secondary microstrip line is provided with one of the secondary stubs. Resonators are provided between four end points of the primary microstrip line and the primary stubs. The antenna structure supports WiFi 6E/WiFi 7 frequency bands including the 2 GHz, 5 GHz and 6 GHz bands, has characteristics of horizontal polarization and omnidirectionality, and effectively satisfies the needs for miniaturized multi-band and wide band antennas.
