The invention discloses a near-field imaging Vivaldi antenna of 30-40 GHZ millimeter waves, and relates to the technical field of communication, electromagnetic field energy dissipation of upper and lower exponential type curve edges within 30-40 GHZ is reduced by redesigning the shapes of the exponential type curve edges, thereby increasing the gain within the frequency band, reducing side lobesand broadening the effective frequency band within 30-40 GHZ. The shapes of the gaps are redesigned, so that the directions of some original messy currents of the empennage can be kept consistent withthe main radiation direction, the messy currents are reduced, and the gain is enhanced; the director is additionally arranged, so that an electric field different from the main radiation direction isfurther reduced, an electromagnetic field in the main radiation direction is enhanced, the cross polarization phenomenon is inhibited more obviously, and the gain effect is improved. 本发明公开了一种30-40GHZ毫米波的近场成像的Vivaldi天线，涉及通信技术领域
