Abstract
This thesis presents simulation data on array operation in wideband

communication systems. It is shown that array structures with closer

inter-element spacing outperform structures with much larger

inter-element spacing. It is also shown that circular structures

outperform linear structures. This performance difference between the

classifications of arrays is due largely to the circular array's

ability to handle high levels of interference. Even though a

diversity combining scheme (MRC) was used in the simulator, the

arrays provided interference rejection capabilities due to the closely

spaced antenna elements. Though diversity does provide a gain in received

signal, relative to the faded signal, realized diversity gain only

comes about once interference has been mitigated. This thesis

work showed that in an environment with a lot of interferers, the

rejection of those interferers by an array is of utmost importance,

even more than fading mitigation.
