The invention discloses a novel butterfly-shaped slotted broadband terahertz antenna, which belongs to the field of terahertz antennas. The antenna comprises a dielectric substrate, a radiation patchand a lumped port exciter. The radiation patch comprises a central patch arranged in the center of the dielectric substrate, two patch wings symmetrically arranged on the two sides of the central patch respectively, and a microstrip transmission line connecting the central patch and the lumped port exciter. The Central patch is circular; the patch wings are fan-shaped, and a connecting line of thecenters of the two patch wings penetrates through the center of the dielectric substrate; the microstrip transmission line is perpendicular to the connecting line of the centers of the two patch wings; a plurality of rectangular grooves are formed in the sectors of the patch wings; openings are formed in the portions, at the front ends of the sectors, of the rectangular grooves; and the rectangular grooves located in the
