Many existing numerical techniques used to analyze wire antennas assume the current distribution on the wire to be one‐dimensional (1D). This assumption imposes geometric constraints on the ratio of the wire radius to the discretized antenna segment length. Moreover, many kernel approximations are so inaccurate that higher‐order basis functions for wire modeling are unthinkable. More accurate kernel models are possible, but generally result in infinite series or require complicated integration rules. This work presents a new generalized approach to the modelling of cylindrical wire antennas. The method is not plagued by the aforementioned geometric restrictions and can be extended to model the higher‐order behavior of wires. The numerical results show the method to be both stable and robust. © 2006 Wiley Periodicals, Inc.
