Abstract:

A near-field antenna is provided, which includes: a first dipole antenna, formed along a first axis, having a first meandering shape and a second dipole antenna, formed along a second axis different from the first axis, having a second meandering shape. The antenna also includes (i) a power amplifier configured to feed electromagnetic signals to at least one of the first and second dipole antennas, (ii) an impedance-adjusting component configured to adjust an impedance of at least one of the first and second dipole antennas, and (iii) switch circuitry configured to switchably couple the first dipole antenna, the power amplifier, the second dipole antenna, and the impedance-adjusting component.
