Claim:
1. A hexaferrite slant and slot MIMO antenna for mobile devices, the antenna comprising: a system board; a ground plane extending along a bottom surface of the system board, wherein the ground plane has a Y-shaped slot; a first lumped port and a second lumped port at a first side of the system board; at least two microstrip lines, where a first microstrip line extends from the first lumped port and a second microstrip line extends from the second lumped port in parallel fashion along a top surface of the system board to a second side of the system board and past a narrow end of the Y-shaped slot; and at least one pair of miniature antenna elements attached to the top surface of the system board in contact with the at least two microstrip lines, wherein the miniature antenna elements are slanted at ±45° with respect to a center Z of an X Y coordinate system, and a center of a radiation sphere, located proximate to the Y-shaped slot; where the Y-shaped slot has a narrow end oriented away from the at least one pair of miniature antenna elements, a wide end oriented toward the at least one pair of miniature antenna elements, and an expansion region in which sides of the Y-shaped slot extend in diverging fashion toward the at least one pair of miniature antenna elements.
