NOVELTY - The present invention discloses Three Dimension Graphene-like crystal element having wider band gaps, which includes multiple main lattices in rectangular array formed by piezoelectric material. Each lattice is formed by distributing multiple bonding rods and multiple bonding circles in interlace, and a hollow is formed at the center of the array connecting five lattices, so that the arrayed lattices can be three dimension graphene-like crystal structure having larger band gap effects and multiple resonant modes in the gap, and can be applied for tunable wave filtering elements and oscillators.
