Abstract: PURPOSE: A micro strip spiral antenna is provided to allow the antenna to be used in a small mobile communication device by reducing the vertical volume of the antenna, while reducing manufacturing costs. CONSTITUTION: A micro strip spiral antenna comprises a dielectric substrate(21) having a predetermined dielectric constant and height(h); a grounding surface(22) formed on the dielectric substrate; a slot(23) formed at the center of the grounding surface; two spiral lines(24,25) having a symmetrical structure, and which are formed by the rotation of 180 degrees centering from the center point formed at the bottom of the dielectric substrate; a main feed line(28) having a power distributor arranged at the bottom surface of the dielectric substrate so as to feed power to the two spiral lines; and two feed lines(26,27) branched off from the main feed line and connected to the outer ends of the spiral lines, respectively.
