The Effect of Mutual Coupling on a High Altitude Platform Diversity System Using Compact Antenna Arrays

<table>The theoretical antenna pattern when all six channels of the MIMO-Tetrahedron antenna are activated. The three antenna beams at elevation angle 30 degrees have vertical linear polarization and the three beams at elevation −45 degrees have horizontal linear polarization.</table>
