Claim 16:
17. A method of manufacturing a near-field wireless-power-transmission system the method of manufacturing including:
providing a first dipole antenna that is placed along a first axis;
providing a second dipole antenna placed along a second axis perpendicular to the first axis;
providing a power amplifier configured to feed electromagnetic signals to at least one of the first and second dipole antennas;
providing an impedance-adjusting component configured to adjust an impedance of at least one of the first and second dipole antennas;
providing circuitry for coupling the at least the first dipole antenna and the second dipole antenna; and
coupling, the reflector, the switch circuitry, the power amplifier, the impedance-adjusting component, and the first and second dipole antennas together, the switch circuitry being configured to:
(i) switchably couple the first dipole antenna to the power amplifier and the second dipole antenna to the impedance-adjusting component, or
(ii) switchably couple the second dipole antenna to the power amplifier and the first dipole antenna to the impedance-adjusting component; and

the switch circuitry further being configured to:
in response to a request from a wireless-power receiving device for a particular amount of power, increment or decrement a power level of electromagnetic waves output by the near-field wireless-power-transmission system based on a power threshold, wherein incrementing or decrementing the power level includes adjusting one or more settings of the power amplifier, the impedance-adjusting component, or both.
