A method of slant-polarization energy transfer includes: at least one of: transmitting a first slanted polarization signal by: transmitting a first component signal of a first polarization from at least one first antenna element; and transmitting a second component signal of a second polarization from at least one second antenna element, the at least one first antenna element and the at least one second antenna element being complementary antenna elements; or receiving a second slanted polarization signal by: receiving a third component signal of the first polarization with the at least one first antenna element; and receiving a fourth component signal of the second polarization with the at least one second antenna element.
