This research is proposed the designing of the Minkowski fractral dipole antenna for altimeter system. The fractal antenna is designed by using Minkowski geometric structure that is rectified by forth step interration. The proposed structure is fabricated on brass and adding the reflector behind the main antenna for better radiation pattern in uni-direction at center frequency of 4.3 GHz. From antenna measurement, the return loss is -30.035 dB, beamwidth of 150 MHz and gain 10.6 dBi.
