<p>Steerable antenna (1) comprising: a first antenna group comprising M antenna elements (5), a second antenna group comprising N antenna elements (5), said N antenna elements (5) surrounding the M antenna elements (5) of first antenna group, switching means (100) coupled to the N antenna elements (5) of second antenna group and a controller (110) programmed for sequentially switching to be active and at different times successive antenna subgroups of second antenna group, while switching at same different times other antenna elements (5) of same second antenna group to be passively terminated in different possible loads. The steerable antenna (1) also comprises L inner termination groups (215) and L inner termination switches (205), 1≤L≤M, allowing modifying the termination loads of the antenna elements (5) of first antenna group.</p> |
