An airship platform is planned to be used as a host for conformal wideband array. Its surface allows the assembly of a very large array including many elements. Full modeling of this array cannot be performed with a modeling tool based on method of moment (MoM) as it is too time consuming. Thus, an approximate method must be used for such a large array. The chosen radiating element is a spiral antenna that will be modeled with MoM and integrated in a 1D circular array. Coupling between elements will be evaluated before being neglected in the approximate method. Finally, array radiation patterns for full MoM and the approximate method will be compared.
