This paper presents the design of a dual band micro strip antenna for Ku band application. The antenna is designed as a patch with two slots. The result shows that the return loss of-42dB and -43dB is achieved at resonant frequencies of 11.95GHz and 14.248 GHz respectively. Satisfactory radiation patterns have also been obtained through simulation. The maximum gain in frequency band is 7.2dB. The antenna is design and simulated by CST Microwave Studio software.
