Abstract
Designing antennas for modern radar and communications applications often requires the evaluation of the antenna’s ultra-wide band (UWB) operation capabilities. Identifying the appropriate electromagnetic modeling tools for UWB antennas can be challenging, since such antennas come in a wide-variety of configurations that range from thin-wire types to complex structures such as spirals, bow-ties, etc. The triangular surface patch method of moments (MoM) formulation1,2 is one popular modeling approach. The surface mesh allows flexibility in modeling detailed antenna features. Since the elements of the MoM impedance matrix, or [Z], must be recomputed for each new frequency, the computation of antenna performance over an wide frequency range can take a long time.
