The invention discloses a channel loaded bow-tie electromagnetic band gap antenna which comprises an electromagnetic band gap structure. The antenna is characterized in that: the bow-tie antenna is supported by a supporting layer and is arranged on the electromagnetic band gap structure; one end of a Balun is connected with the bow-tie antenna to feed current to the bow-tie antenna by passing through a through hole arranged in the center of a substrate of the electromagnetic band gap structure, and the other end is connected with an SMA. In the antenna, capacitive load and inductive load can realize self-balance in broad frequency band, and the impedance and the radiation mode in the antenna are stable, thus expanding the impedance bandwidth of the antenna; and the antenna gain is not affected while expanding the operation bandwidth of the antenna; the distance between the antenna and the electromagnetic band gap structure can be rather less than a quarter wavelength, and broad operating frequency range and g
