Claim:
A method, comprising: providing a radiative plane in an antenna, wherein the radiative plane comprises a primary radiative element and a plurality of separate parasitic radiative elements spaced from the primary radiative element, the primary radiative element having a first side and an opposing second side, the first and second sides parallel to a first axis, and wherein at least two of the parasitic radiative elements are arranged on the first side and at least another two of parasitic radiative elements are arranged on the second side, wherein said at least two of the parasitic radiative elements arranged on the first side comprise a first parasitic radiative element having a longitudinal axis substantially parallel to the first axis and a second parasitic radiative element having a longitudinal axis substantially perpendicular to the first axis, and wherein said at least another two of the parasitic radiative elements arranged on the second side comprise a third parasitic radiative element having a longitudinal axis substantially parallel to the first axis and a fourth parasitic element having a longitudinal axis substantially perpendicular to the first axis; arranging a ground plane spaced from the radiative plane, wherein the ground plane comprises a plurality of separate slots, each slot having a middle section connected to two opposite end sections, and said plurality of slots comprise a first slot and a second slot, wherein the middle section of the first slot has a longitudinal axis substantially parallel to the first axis and the middle section of the second slot has a longitudinal axis substantially parallel to the first axis; and arranging a plurality of feed lines adjacent to but electrically isolated from the ground plane, wherein said plurality of feed lines comprise a first feed line and a second feed line, and wherein one end of the first feed line is located adjacent to the middle section of the first slot, and one end of the second feed line is located adjacent to the middle section of the second slot.
