1. A filter system comprising:
a first resonator group; and
a second resonator group,
wherein the first resonator group comprises:
a first resonator having a first resonant frequency, and
a second resonator having a second resonant frequency different from the first resonant frequency,
wherein the second resonator group comprises:
a third resonator having a third resonant frequency different from the first and second resonant frequencies, and
a fourth resonator having a fourth resonant frequency different from the first, second, and third resonant frequencies, and
wherein a first length difference between the first resonator and the second resonator is less than a second length difference between the second resonator and the third resonator, and a third length difference between the third resonator and the fourth resonator is less than the second length difference between the second resonator and the third resonator,
wherein the first resonator group and the second resonator group are directly adjacent to each other, and
wherein the second resonator and the third resonator are directly adjacent to each other.
