Abstract
FEKO is a 3D simulation tool for the analysis of electromagnetic fields. FEKO can solve the problem of any structural type with a very comprehensive MoM code or other tailored code. In this paper, a radiation pattern for conformal phased array antenna on the surface of a PEC finite cylinder is calculated using FEKO 4.0. The simulation results accord with the true characteristics of conformal array antenna on a finite length cylinder. The results also can meet with which in related reference. So, the simulation can be proved to be correct. Furthermore, the patterns of different scanning angle for this conformal phased array are simulated and some important parameters of the array patterns are given.
Highlights
A conformal antenna is an antenna that conforms to something; in our case, it conforms to a prescribed shape
The specific coordinate and model of a conformal antenna are shown in Figure 1, which is a microstrip antenna described as an element of a conformal phased array
A good radiation pattern of a conformal array antenna is simulated with FEKO 4.0
Summary
A conformal antenna is an antenna that conforms to something; in our case, it conforms to a prescribed shape. The purpose is to build the antenna so that it becomes integrated with the structure and does not cause extra drag. The purpose can be that the antenna integration makes the antenna less disturbing, less visible to the human eye; for instance, in an urban environment. Antennas of cylindrical geometry can be analyzed in a number of ways, among which are the finite element method, the auxiliary sources method, the method of moments (MOM), etc. The method of moments can be employed in both spectral and spatial domains. Both solutions work well until the cylinder is electrically small (Alexander Svezhentsev, 2004, 629). We use MOM to simulate the conformal phased array by FEKO 4.0
