Patent ID: 8026860

Claim:
An apparatus, comprising: an antenna device including several electrically small dipole antennas coupled in parallel to one another, each of the dipole antennas extending a different length than any other of the dipole antennas, and the dipole antennas each corresponding to a resonator with a different resonant frequency to collectively define a number of operating frequencies, the dipole antennas each including: a feed point; two dipole ends; two inductor devices, the feed point being positioned between the two dipole ends and between the two inductor devices to provide a connection to transmit or receive signals through the antenna device; and two electrically conductive members each extending from the feed point to a respective one of the two inductor devices, the two inductor devices each being positioned closer to a respective one of the two dipole ends than the feed point for each of the dipole antennas.
