Abstract: Provided is an antenna, which integrates a waveguide structure and an ordinary feeding network, thereby avoiding a complex structure. The antenna can be used as a base station antenna and wifi antenna. The antenna includes: a waveguide radiator, including a lower radiation panel and at least one waveguide structure provided on the lower radiation panel; an upper-layer radiator, including an upper radiation panel, wherein the upper radiation panel is provided with at least one opening, and the opening is corresponding to the waveguide structure one by one; and a feeding network, connected to each waveguide structure, wherein at least a part of the feeding network is provided between the lower radiation panel and the upper radiation panel, and has a gap with the lower radiation panel and the upper radiation panel, respectively.

Abstract: An antenna and a combined antenna are provided. The antenna comprises: a housing in which a first port and a second port are formed; a feeding network unit, which is disposed inside the housing and comprises a waveguide power divider connecting the first port and the second port, wherein the waveguide power divider is configured for dividing the electromagnetic wave transmitted from the first port to the second port, or merging the electromagnetic wave transmitted from the second port to the first port; a radiating unit, which comprises a radiator disposed on the housing and close to the second port. The antenna has the advantages of low loss, being suitable for high-power transmission. In addition, the antenna is relatively simple in structure, and therefore, is beneficial to reduce the overall volume of the antenna, so as to meet the miniaturization design requirements of the antenna.
