摘要： A low-sidelobe plate array antenna includes a radiation layer and a feed layer. The radiation layer is superimposed on the feed layer and includes a first plate and a radiation array disposed on the first plate. The radiation array is formed by n2 radiation units which are distributed in 2(k-1) rows and 2(k-1) columns. Each radiation unit in the radiation layer is constituted by two first radiation assemblies and two second radiation assemblies. Each first radiation assembly comprises a first rectangular bar, a first rectangular cavity, a second rectangular cavity and a third rectangular cavity. The first rectangular cavity, the second rectangular cavity and the third rectangular cavity in the first radiation assembly are stacked in presence of an azimuth deviation to form a three-layer coupled structure, and the first rectangular bar located in the first rectangular cavity can better restrain cross polarization and reduce the sidelobe.

摘要： A broadband panel array antenna includes a polarization layer, a radiating layer and a feed layer which are sequentially stacked from top to bottom. The feed layer is used for converting a single path of TE10 mode signals into a plurality of paths of same-power in-phase TE10 mode signals and transmitting the plurality of paths of TE10 mode signals to the radiating layer. The radiating layer is used for radiating the plurality of paths of TE10 mode signals from the feed layer to a free space. The polarization layer is used for rotating the polarization direction of an electric field generated by the radiating layer to reduce the side lobe in an E-plane direction diagram and an H-plane direction diagram. The broadband panel array antenna has the advantages of being low in side lobe, high in gain and efficiency, and low in machining cost.
