1. A handheld screening device comprising:
- a two-dimensional 2D multiple input-multiple-output (MIMO) antenna array including a plurality of antennas, the plurality of antennas including a first plurality of antennas of a first size arranged in a first plurality of first rows and first columns and a second plurality of antennas of a second size, which is less than the first size, arranged in a second plurality of second rows and second columns, wherein an outer periphery of the first plurality of antennas is within a width between two of the second rows and two of the second columns;
an input mechanism configured to select an operation mode from at least a first operation mode, a second operation mode and a third operation mode;
a processor configured to determine a group of antennas of the plurality of antennas, wherein the number of antennas in the group is based on the selected operation mode, and to control the group of antennas to emit or to receive electromagnetic waves, whereinthe number of antennas included in the group is a first number of antennas when the first operation mode is selected,the number of antennas included in the group is a second number of antennas, which is greater than the first number of antennas, when the second operation mode is selected, andthe number of antennas included in the group is a third number of antennas, which is greater than the second number of antennas, when the third operation mode is selected; and
the processor is further configured to determine one or more processed layers, wherein the one or more processed layers are based on the selected operation mode, whereinthe one or more processed layers is a single layer when the first operation mode is selected,the one or more processed layers is a default number of layers, which is greater than the single layer, when the second operation mode is selected, andthe one or more processed layers are all received layers, which is greater than the default number of layers, when the third operation mode is selected.

7. A method for operating a handheld screening device that includes a two-dimensional 2D multiple input-multiple-output (MIMO) antenna array with a plurality of antennas to emit electromagnetic waves, the plurality of antennas including a first plurality of antennas of a first size arranged in a first plurality of first rows and first columns and a second plurality of antennas of a second size, which is greater than the first size, arranged in a second plurality of second rows and second columns, wherein an outer periphery of the first plurality of antennas is within a width between two of the second rows and two of the second columns, the method comprising:
-
selecting an operation mode from at least a first operation mode, a second operation mode and a third operation mode, determining a group of antennas of the plurality of antennas, wherein the number of antennas in the group is based on the selected operation mode, emitting electromagnetic waves from the determined group of antennas or receiving electromagnetic waves from the determined group of antennas, wherein the number of antennas included in the group is a first number of antennas when the first operation mode is selected, the number of antennas included in the group is a second number of antennas, which is greater than the first number of antennas, when the second operation mode is selected, and the number of antennas included in the group is a third number of antennas, which is greater than the second number of antennas, when the third operation mode is selected; and determining one or more processed layers, wherein the one or more processed layers are based on the selected operation mode, wherein the one or more processed layers is a single layer when the first operation mode is selected, the one or more processed layers is a default number of layers, which is greater than the single layer, when the second operation mode is selected, and the one or more processed layers are all received layers, which is greater than the default number of layers, when the third operation mode is selected. - View Dependent Claims (8, 9, 10, 11)
