Abstract :
In this study, wire antenna systems are analyzed via two well-known techniques: the finite-difference time-domain and method of moments. The advantages and disadvantages of the techniques and their parameter requirements are discussed on a canonical test case. Various antenna systems are designed and their performances are tested under different environmental conditions with variety of parameters. Different ground screens are modeled over a lossy ground and their effects on antenna gain and radiation patterns are investigated. Both broad-side and end-fire arrays are simulated and electronic beam steering is simulated.
