We propose a 1-wavelength loop type dielectric chip antenna that meets the demand for antennas with unidirectional radiation patterns for portable communication devices. The structure of the proposed antenna is shown. The radiating element printed loop is on the top of the cube. A feeding strip line is on one of the vertical face of the cube and a shorted plate parallel to the feeding strip line is on the same face. The conductive plane is on the bottom of the cube. By printing all of conductive elements on a ceramic cube this novel antenna is easy to fabricate.
