A METHOD OF DESIGNING WEIGHT VECTORS FOR A DUAL BEAM ANTENNA WITH ORTHOGONAL POLARIZATIONS |
摘要 |
<p>The present invention relates to a method of generating two beams, having orthogonal polarizations, covering a selected area using an antenna (20) comprising multiple dual-polarized array elements (11). Each dual-polarized array element having a first phase center (18) associated with a first polarization and a second phase center (18) associated with a second polarization. The method comprises: designing a first weight matrix having a first non-zero weight vector for the first polarization and a second non-zero weight vector for the second polarization, calculating a second weight matrix based on the weight vectors of the first weight matrix, and applying the first and second weight matrix to the dual-polarized array elements to generate a second beam covering the selected area.</p> |
