1. An antenna device, comprising:
a dielectric support;
a first conductor disposed on the dielectric support, the first conductor comprising:
a signal feed terminal;
a first signal portion electrically connected to the signal feed terminal and configured to have a first electromagnetic field amplitude at a first resonant frequency when the signal feed terminal is driven at the first resonant frequency; and
a second signal portion electrically connected to the signal feed terminal and configured to have a second electromagnetic field amplitude at the first resonant frequency when the signal feed terminal is driven at the first resonant frequency,
wherein the first electromagnetic field amplitude is larger than the second electromagnetic field amplitude; and
a second conductor disposed on the dielectric support and comprising:
a reference feed terminal;
a first reference portion electrically connected to the reference feed terminal and spaced from the first signal portion by a first gap distance, the first gap distance configured to provide a first amount of coupling between the first signal portion and the first reference portion at the first resonant frequency; and
a second reference portion electrically connected to the reference feed terminal, spaced from the second signal portion by a second gap distance greater than the first gap distance, and configured to provide a second amount of coupling between the second signal portion and the second reference portion at the first resonant frequency, the first amount of coupling being larger than the second amount of coupling.
