Claim 4

A method for assigning frequency groups to cosine-squared antennas within a cell cluster sited as defined by claim 1 wherein each cell cluster contains 37 cells, and when the centerpoint is an antenna site, comprising assigning each of the cells in individual frequency group from a set of five frequency groups in accordance with FIG. 5 of the drawing, in which individual frequency assignments from the set are shown as numerals within corresponding cells.

Claim 5

A method for assigning frequency groups to cosecant-squared antennas sited as defined by claim 1, when each cell cluster contains 19 cells, when there exist four types of cell clusters, and when the centerpoint of each cluster is an antenna site, comprising assigning each of the cells an individual frequency group from a set of seven frequency groups and thereby forming a type I cell cluster, a type II cell cluster, a type III cell cluster and a type IV cell cluster in accordance with FIG. 6A of the drawing, and arranging the type I cell clusters, the type II cell clusters, the type III cell clusters, and the type IV cell clusters in accordance with FIG. 6B of the drawing, in which individual frequency assignments from the set are shown as Arabic numerals within corresponding cells, and in which cell cluster types are shown as Roman numerals within corresponding cell clusters.

Claim 6

An array comprised of cosine-squared antennas, each antenna in the array being associated with a corresponding one of a plurality of like hexagonal cells, the cells being arranged in a dense hexagonal cellular grid system in a manner that a circle is circumscribed around each cell, all cells and circles circumscribed thereabout are classified into like hexagonal cell clusters, a center cell is located in each such cell cluster, a centerpoint is located within each such center cell, a cosine-squared antenna is located at least adjacent each such centerpoint, and a cosine-squared antenna is located at least adjacent to a point on each circumscribed circle within each cell cluster exclusive of circles circumscribed about such center cells, which point is that point on each such circumscribed circle which is closest to such centerpoint within such center cell within such cell cluster.

Claim 7

An array comprised of cosine-squared antennas, each antenna in the array being associated with a corresponding one of a plurality of like hexagonal cells, the cells being arranged in a dense hexagonal cellular grid system in a manner that a circle is circumscribed around each cell, all cells and circles circumscribed thereabout are classified into like hexagonal cell clusters, a center cell is located in each such cell cluster, a centerpoint is located within each such center cell, a cosine-squared antenna is located at least adjacent each such centerpoint, and a cosine-squared antenna is located at least adjacent to a point on each circumscribed circle within each cell cluster exclusive of circles circumscribed about such center cells, which point is that point on each such circumscribed circle which is closest to such centerpoint within such center cell within such cell cluster.

Claim 8

The array defined by claim 5, wherein each cell cluster includes 19 cells.

Claim 9

The array defined by claim 5 wherein antennas within each cell cluster are assigned individual frequency groups so as to create cell clusters which are symmetrical about their corresponding centerpoints and which have diagonals and medians which are perpendicular to each other within each cell cluster.

Claim 10

The array defined by claim 7, wherein each antenna in each cell within each cell cluster has an individual frequency group selected from a set of five frequency groups.

Claim 11

The array defined by claim 7, wherein each antenna in each cell within each cell cluster has an individual frequency group selected from a set of seven frequency groups.

Claim 12

The array defined by claim 5, wherein the cell clusters are classified into differing types and are so ordered that all cell clusters of a common type are separated from each other.

Claim 13

The array defined by claim 10, wherein there are four types of cell clusters.
