PURPOSE: A micro chip antenna is provided to allow for a wide frequency bandwidth and improve gains by decreasing the leakage current, while reducing the size of the antenna. CONSTITUTION: A micro chip antenna(100) comprises a feeder hole(20) formed at a width-wise side surface of a dielectric and plated with a conductor; an upper pad(31) having a length of 2 to 4 percent from an end of the total length of a top surface of the dielectric; a lower pad(32) having a length of 2 to 4 percent from an end of the total length of a bottom surface of the dielectric, and which is disconnected from the upper pad; a radiation patch(60) including a slot(40) having a length of 2 to 4 percent from the upper pad with respect to the total length of the top surface of the dielectric, a center strip line(51) which is stripped to have a length of 10 to 15 percent of the total length of the top surface of the dielectric and a width of 60 to 80 percent of the total width of the top surface of the dielectric, and a first array strip line(52) and a second array strip line(53) which are stripped at both sides of the center strip line, respectively; and a ground surface(70) having a length of 4 to 8 percent from the other end of the total length of the bottom surface of the dielectric, and a width of 8 to 12 percent of the total width of the bottom surface of the dielectric.
