This was one cubit wide, covering the space directly above the middle of the altar (Maaseh Choshev 6:5). According to the opinion that the altar was 3 cubits high, it began 1 1/2 cubits (27') above the ground, and extended upward to 2 1/2 cubits above the ground. Some say that it protruded to catch any stray coals falling from the altar (Targum Yonathan on Exodus 27:5).
However, the Septuagint translates mikhbar here as esxapon, a hearth or place for offerings. It was made out of heavy copper netting to provide draft for the fire (cf. Josephus 3:7:8).
