Capacity Evaluation of a High Altitude Platform Diversity System Equipped with Compact MIMO Antennas

           A. Mohammed and T. Hult

Full text:  PDF


In this paper we address the potential gain of using compact MIMO antenna array configurations in conjunction with High Altitude Platforms (HAPs) diversity techniques in order to increase the capacity in HAP communication systems. For this purpose, we also propose a novel compact MIMO antenna which we denote as the “MIMO-Octahedron” and compare its performance with the vector element antenna. Simulation results show that the MIMO-Octahedron antenna provides superior performance to the vector element antenna and the single HAP case.
