Claim 4:
5. A monopole antenna, comprising: a radiating element, wherein the radiating element has a first curved outer surface that is rotationally symmetric about a longitudinal axis extending through the monopole antenna, wherein a first diameter at a first end of the radiating element is less than a second diameter at a second end of the radiating element;
the first curved outer surface is defined, across height, by a first polynomial existing between an inner boundary and an outer boundary, wherein the inner boundary is defined by a second polynomial having the coefficients:

[−1.8260e+07,3.8143e+06,−2.9036e+05,9.2911e+03,−99.4808,0.3379,0.0052]

wherein the outer boundary is defined a third polynomial having the coefficients:

[−1.7632e+07,3.7703e+06,−2.9922e+05,1.0539e+04,−158.8708,1.5534,0.0075]

wherein the predetermined bandwidth is at least 750-6,000 MHz; and
a ground plane disposed opposite the radiating element such that an electric field is generated by the radiating element using the ground plane as a counterpoise, wherein the ground plane has a second curved outer surface that is rotationally symmetric about the longitudinal axis, wherein a first diameter at a first end of the ground plane is less than a second at a second end of the ground plane, wherein the first end of the radiating element is disposed adjacent the first end of the ground plane.
