Abstract
A variably controlled stagger antenna array architecture is disclosed. The array employs a plurality of driven radiating elements that are spatially arranged having each radiating element or element groups orthogonally movable relative to a main vertical axis. This provides a controlled variation of the antenna array's azimuth radiation pattern without excessive side lobe radiation over full range of settings.
Claims24
An antenna for a wireless network, comprising
- a generally planar reflector;
- a plurality of radiators in a vertical column relative to the reflector wherein a first plurality of the radiators and a second plurality of the radiators are linearly displaceable horizontally with respect to each other and with respect to a third plurality of radiators that is fixed along the vertical column;
- and
- one or more mechanical actuators coupled to the first plurality of the radiators and the second plurality of radiators to provide linear horizontal displacement of the first plurality of the radiators and the second plurality of the radiators, apart or toward each other;
- wherein the plurality radiators are reconfigurable horizontally from a first configuration where the radiators are all aligned in the vertical column, to a second configuration where the radiators are configured in three columns, each column having plural radiators generally aligned.
A mechanically variable beam width antenna, comprising:
- a generally planar reflector;
- a first plurality of linearly horizontally displaceable radiators configured in a first column adjacent the reflector;
- a second plurality of linearly horizontally displaceable radiators configured in a second column adjacent the reflector;
- a third plurality of radiators configured in a fixed third column adjacent the reflector;
- at least one mechanical actuator coupled to the first plurality of radiators and the second plurality of radiators, the at least one mechanical actuator to provide linear horizontal displacement of the at least some of the radiators, apart or toward each other with respect to the third column,
- wherein the first plurality of radiators and the second plurality of radiators are movable relative to each other horizontally wherein radiators are arranged in a line from a first configuration wherein the first and second columns are spaced a first distance apart, to a second configuration wherein the first and second columns are spaced a second distance apart.
A method of adjusting signal beam width in a wireless antenna having a plurality of radiators at least some of which are movable in a direction generally parallel to a plane of a reflector, the method comprising:
- providing the plurality of radiators in a first configuration where the radiators are all aligned in a single column generally parallel to the reflector axis to provide a first signal beam width;
- and
- adjusting a first plurality of the radiators and a second plurality of the radiators by mechanical actuators configured to provide linear horizontal displacement to the first plurality of the radiators and to a second plurality of the radiators, in a linear horizontal direction that is generally orthogonal to the axis of the column, to a second configuration wherein the plurality of radiators are configured in at least three separate columns of plural radiators to provide a second signal beam width.
A method of adjusting signal beam width in a wireless antenna having a plurality of radiators at least some of which are movable in a direction generally parallel to a plane of a reflector, the method comprising:
- providing the plurality of radiators in a first configuration wherein the plurality of radiators are aligned in at least three separate columns of plural radiators to provide a first signal beam width;
- and
- adjusting at least some of the plurality of radiators by mechanical actuators configured to provide linear horizontal displacement to the at least some of the plurality of radiators, in a horizontal direction that is generally orthogonal to the axis of the columns to a second configuration, wherein the plurality of radiators are configured in at least three separate columns of plural radiators and wherein at least two of the columns have a different spacing between the axes of the columns than in said first configuration, to provide a second signal beam width.
