1. A modular wireless power transfer system for transmitting alternating current (AC) wireless signals, the AC wireless signals including wireless power signals and wireless data signals, the wireless power transfer system comprising:
a first wireless transmission system configured to receive input power from an input power source and generate AC wireless signals based, at least in part, on the input power, the first wireless transmission system comprising:
a first transmission antenna comprising:
a first antenna portion including a first terminal and a second terminal; and
a second antenna portion including a third terminal and a fourth terminal,
wherein the second terminal of the first antenna portion is in electrical connection with the third terminal of the second antenna portion and wherein each of the first antenna portion and the second antenna portion is configured to couple with one or more other antennas; and
an integrated circuit comprising:
a first transmission controller configured to provide first driving signals for driving the first transmission antenna; and
a demodulation circuit configured to receive the wireless data signals from a wireless receiver system and decode the wireless data signals; and
a first power conditioning system configured to receive the first driving signals and generate the AC wireless signals based, at least in part, on the first driving signals; and
one or more secondary wireless transmission systems, each of the one or more secondary wireless transmission systems comprising:
a secondary transmission antenna comprising:
a third antenna portion including a fifth terminal and a sixth terminal; and
a fourth antenna portion including a seventh terminal and an eighth terminal, wherein the sixth terminal of the third antenna portion is in electrical connection with the seventh terminal of the fourth antenna portion,
wherein each of the third antenna portion and the fourth antenna portion is configured to couple with one or more of another secondary transmission antenna, the first antenna portion, the second antenna portion, one or more receiver antennas, or combinations thereof,
wherein the fourth antenna portion is configured to receive the AC wireless signals from the second antenna portion, transmit the AC wireless signals to a receiver antenna of the wireless receiver system, and provide AC wireless signals to the third antenna portion, and wherein the third antenna portion is configured to receive the AC wireless signals from the fourth antenna portion, transmit the AC wireless signals to another receiver antenna of another wireless receiver system, and provide AC wireless signals to the fourth antenna portion.
