Abstract
A tri-column antenna array architecture, containing a plurality of active radiating elements that are spatially arranged on a modified reflector structure is disclosed. Radiating elements disposed along (P1 and P2) outlying center lines are movable and provided with compensating radio frequency feed line phase shifters so as to provide broad range of beam width angle variation of the antenna array's azimuth radiation pattern.
Claims19
An antenna for a wireless network, comprising:
- a reflector comprising first, second and third reflector panels;
- first, second and third columns of plural radiator elements coupled to respective reflector panels, the second column of radiator elements configured between the first and third columns of radiator elements;
- wherein the first and third radiator elements are movable relative to each other to alter the spacing of the first and third columns of radiator elements,
- wherein the first and third reflector panels have generally planar surfaces which are defined by a Y-axis and a Z-axis parallel to the plane of the reflector surface and an X-axis extending out of the plane of the reflector, wherein said columns of plural radiator elements are parallel to the Z-axis, and wherein the radiator elements are movable only in the Y direction and the reflector panels are fixed to each other.
A mechanically variable beam width antenna, comprising:
- a shaped single piece reflector structure having a plurality of generally planar reflector panels, the plurality of reflector panels including a center panel and first and second outer panels fixed to each other, wherein the center panel is configured above the outer panels in a radiating direction;
- a first plurality of radiators coupled to the first outer panel and configured in a first column;
- a second plurality of radiators coupled to the second outer panel and configured in a second column;
- a third plurality of radiators coupled to the center panel and configured in a third column;
- wherein the first and second plurality of radiators are movable relative to each other from a first configuration wherein the first and second columns of radiators are spaced apart a first distance in a wide beam width setting to a second configuration where the first and second columns of radiators are spaced apart a second greater distance in a narrower beam width setting.
A method of adjusting signal beam width in a wireless antenna having a plurality of radiators configured on at least three reflector panels including two coplanar outer panels and a non-coplanar center panel forming a fixed common reflector, wherein radiators on the two outer panels are movable, the method comprising:
- providing the radiators in a first configuration where the outer panel radiators are spaced apart a first distance to provide a first signal beam width;
- and
- moving the radiators in a direction generally parallel to the coplanar surface of the outer panels to a second configuration spaced apart a second distance to provide a second signal beam width.
