Claim:
1. A method to design an antenna, the method comprising: providing, by a computer, initial values for an antenna geometry; providing, by a computer, a desired frequency range for the antenna; providing, by a computer, a subtended angle for the antenna; performing, by a computer, an electromagnetic simulation for the antenna, based on the initial values for the antenna geometry, the desired frequency range and the subtended angle, thereby obtaining scattering parameters and far-field patterns for the antenna; evaluating, by a computer, a cost function for the antenna, based on the scattering parameters, the far-field patterns and the antenna geometry; determining an optimized design for the antenna, based on the initial values for the antenna geometry, the desired frequency range, the subtended angle, the scattering parameters, the far-field patterns and the cost function, thereby obtaining an optimized antenna, wherein the cost function comprises an input reflection coefficient, the input reflection coefficient comprising a return loss error, a standing-wave ratio, and a maximum error for the return loss error.
