1. A signal coupling system, comprising:
a directional coupler, comprising:
a first conductor:
comprising a first end and a second end; and
arranged along a first plane;
a second conductor:
comprising a third end and a fourth end; and
arranged as a plurality of windings along a second plane;
a transceiver, operably conducted to the first end; and
an antenna, operably conducted to the second end;
wherein the second conductor is configured to couple to the first conductor for an electrical signal conductivity at the first conductor; and
wherein, the directional coupler is further configured to conduct a first electrical signal from the first end at a first power to the second end at a second power, and to couple the first electrical signal to the third end at a third power;
wherein the directional coupler is configured to have an operational frequency, and wherein a length of the first conductor is shorter than one-fourth of a wavelength of the operational frequency.
