Abstract: A quadri-polarization diversity antenna system is disclosed.
According to embodiments of the present disclosure, an antenna system includes an antenna array including a first column of dual-polarized antenna units and a second column of dual-polarized antenna units. Each of the dual-polarized antenna units includes a first antenna element and a second antenna element perpendicularly crossing each other. In each column, the first antenna elements are conductively connected to form a first subarray and the second antenna elements are conductively connected to form a second subarray. The antenna system further includes an RF matrix that selectively adjusts phases of RF input signals to generate RF output signals provided to the subarrays. When the RF output signals are radiated by the dual-polarized antenna units, a first beam with +/−45° polarizations and a second beam with 0°/90° polarizations are formed, and the first beam and the second beam are formed toward spatially different directions from each other.-
