Abstract
A base station antenna array comprises a ground plane and a parallel array of antennas above the ground plane. The antennas each have a progression of radiating elements whose length increases in a direction away from the ground plane. A feed is connected to the antenna at a point nearest the ground plane.
Claims61
An antenna assembly comprising:
- an antenna having a flat, fan-shaped body defined by a sinuous conductor following a continuous serpentine path between opposing rays of the fan-shape from an apex end to a distal end of the fan-shaped body;
- and
- a feedpoint coupled to the sinuous conductor on the apex end of the antenna element.
A flat monopole antenna comprising;
- a feedpoint;
- a progression of progressively longer antenna elements of the flat monopole antenna each disposed between a pair of rays extending outwards from the feedpoint, wherein each progressively longer antenna element is connected on a first end to a corresponding end of an immediately previous antenna element of the progression and a second end to a corresponding end of an immediately successive element in the progression.
The flat monopole antenna as in claim 111 wherein the pair of rays further comprise an angle of about one-hundred degrees.
A flat monopole antenna comprising:
- a flat pie-shaped substrate having a pair of edges defining an apex of the pie-shaped substrate;
- and
- a plurality of antenna elements disposed between the opposing edges of the pie-shaped substrate, each antenna element of the plurality of antenna elements joined at a first end to another antenna element of the plurality of antenna elements closer to the apex and joined at a second end to another antenna element of the plurality of elements further from the apex.
A base station antenna array comprising:
- a ground plane;
- and
- an array of generally flat antennas disposed above the ground plane, the antennas each comprising a progression of series-connected radiating elements whose length, spacing and width increases in a direction away from the ground plane.
A base station antenna array comprising:
- a ground plane;
- a parallel array of generally flat antennas above the ground plane, the antennas each having a progression of series-connected radiating elements whose length, spacing and width increases in a direction away from the ground plane;
- and
- a feed connected to the elements at a point nearest to the ground plane.
A base station antenna array comprising:
- a ground plane;
- and
- a spaced array of generally flat antennas disposed above the ground plane, the antennas each having conductors configured as a diverging sinuous or zig-zag progression of end-connected elements, said diverging progression increasing in conductor length, conductor spacing and conductor width from a ground plane end to a distal end.
A base station antenna array comprising:
- a ground plane;
- and
- an array of generally flat antennas above the ground plane, the antennas each having a diverging progression radiating elements configured as a folded linear spiral, said diverging progression increasing in radiating element length, element spacing and element width from the ground plane end to a distal end.
A base station antenna array comprising:
- a ground plane;
- and
- an array of generally flat antennas above the ground plane, the antennas each have a helical spiral conductor with the apex of the spiral closest to the ground plane, said helical spiral having a diverging element length, element spacing and element width from the ground plane to a distal end.
For use in a base station antenna array, generally flat antenna comprising a progression of radiating elements whose length increases in a direction away from a feed connection where at least some of the radiating elements of the progression of elements are connected on a first end to another element of the progression closer to the feed connection and on a second, opposing end to an element of the progression further from the feed connection.
