The invention discloses a double-trapped-wave ultra-wide-band antenna. The double-trapped-wave ultra-wide-band antenna is mainly characterized in that two stepped grooves are formed at the large-head end of a micro-strip radiation patch with respect to the central axis of the micro-strip radiation patch in a bilaterally-symmetrical mode, each stepped groove consists of a first horizontal groove, a second horizontal groove and a vertical groove, the first horizontal groove and the second horizontal groove are equal in length, the sum of the lengths of the first horizontal groove and the second horizontal groove is smaller than the length of the vertical groove, the left-side edge of the first horizontal groove of the first stepped groove formed in the left side coincides with the left-sided edge of the micro-strip radiation patch, the right-side edge of the first stepped groove formed in the right side coincides with the right-sided edge of the micro-strip radiation patch, a semi-closed annular groove is formed in the small-head end of the micro-strip radiation patch, and the length of each stepped groove and the length of the semi-closed annular groove are one half or quarter of the wave length of suppressed mid-band frequency. The double-trapped-wave ultra-wide-band antenna can achieve ultra-wide-band communication and mutual compatible and cooperative communication of mutual interference communication systems.
