Claim 8:
9. 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;
wherein, 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:

[−4.93500e+35,6.42410e+34,−3.84685e+33,1.40487e+32,−3.49753e+30,6.28527e+28,−8.42139e+26,8.56859e+24,−6.68061e+22,3.99837e+20,−1.82823e+18,6.31088e+15,−1.61039e+13,2.93397e+10,−3.59697e+07,2.65028e+04,−8.83888e+00]

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

[−4.55838e+35,5.95257e+34,−3.57632e+33,1.31063e+32,−3.27491e+30,5.90804e+28,−7.94839e+26,8.12231e+24,−6.36156e+22,3.82570e+20,−1.75807e+18,6.10037e+15,−1.56504e+13,2.8669e+10,−3.534904e+07,2.61810e+04,−8.7756e+00]

wherein the predetermined bandwidth is at least 9,000-10,000 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.
