Radiation Pattern Computation of Pyramidal Conformal Antenna Array with Active-Element Pattern Technique

Pyramidal microstrip conformal antenna arrays are analyzed with the use of the Active-Element Pattern (AEP) technique. The active-element patterns of typical elements can be computed effectively by dividing a large antenna, array into small subarrays. This results in a simplified analysis process for a conformal antenna array, and a reduction of the computational resources. Radiation patterns of the pyramidal arrays are computed with the use of the Active-Element Pattern technique, as well as full-wave simulation of the whole array. A comparison of the radiation patterns and computation times with the two methods is given, which illustrates the effectiveness and advantage of the new method.
