Abstract
The embodiments of the present application relate to the technical field of antennas. Disclosed are an antenna and a network device, which aim to optimize the performance of antennas. The specific scheme involves: the antenna comprising an electrically conductive housing and a radiating structure, wherein the electrically conductive housing is used for grounding; the electrically conductive housing comprises an inner cavity, a first opening and a second opening, the first opening and the second opening both communicating with the inner cavity; the size of the first opening in a first direction is greater than or equal to 1λ, λ being the dielectric waveguide wavelength corresponding to the center frequency of the antenna; one end of the radiating structure is electrically connected to the electrically conductive housing; the radiating structure covers part of the second opening, and forms a first slot and a second slot with the electrically conductive housing; the first slot communicates with the first opening in the extension direction of the first slot; and the second slot communicates with the first opening in the extension direction of the second slot. The antenna has the advantages of wide bandwidth, high gain, good radiation pattern circularity, omnidirectional radiation in the horizontal plane, etc., thereby being applicable to scenarios such as WLAN or FTTR.
