According to the electromagnetic band gap structure with the double-band-gap characteristic and the array antenna provided with the electromagnetic band gap structure, the first metal patch and the second metal patch which are different in structural pattern are designed on the laminated structure unit, and the plane size of the electromagnetic band gap structure is reduced while the double-band-gap characteristic of the electromagnetic band gap structure is achieved. Specifically, four C-shaped slotted holes are symmetrically formed in the center of a first metal patch, and the opening sides of the C-shaped slotted holes face the center of a square, so that the equivalent capacitance and the equivalent inductance of the first metal patch of the electromagnetic band gap structure are improved, the band gap of the first metal patch shifts towards low frequency, and the electromagnetic band gap structure can be suitable for the size of a smaller electromagnetic band gap structure; furthermore, the second metal
