1. A method of designing an antenna connected to a feed system including a radio frequency source, the method comprising: choosing minimum and maximum feed system characteristic impedance values; using an iterative antenna design algorithm on a computer where antenna design parameters and a feed system characteristic impedance value are variables to achieve one or more antenna performance objectives; varying said antenna design parameters while varying feed system characteristic impedance values between the minimum and maximum feed system characteristic impedance values until said one or more antenna performance objectives are achieved using said iterative antenna design algorithm; determining a feed system characteristic impedance value from the varied feed system characteristic impedance values which results in said one or more antenna performance objectives; designing the feed system such that said feed system exhibits said determined feed system characteristic impedance value or an approximation of said feed system characteristic impedance value; determining which antenna design parameters result in said antenna performance objectives; and designing the antenna according to said determined antenna design parameters to achieve said one or more antenna performance objectives.
