The aim of this work was to design a rectangular microstrip patch antenna that will operate at a Ku band. The design was done using mathematical or computation method. The frequency of operation of the rectangular microstrip patch antenna designed is 16 GHz (16 x 109 Hz). It was observed from the result that as the values of the dielectric constant is increasing, the dimensions- height, length and width of the antenna decrease. For instance, when the value of the dielectric constant increased from 2.0 to 2.5, the patch antenna height decreased from 0.633 mm to 0.566; the width decreased from 7.65 mm to 7.09 mm, and length changed from 6.48 mm to 5.82 mm. It was concluded that the higher values of dielectric constant will result in the decrease in the size of a rectangular microstrip patch antenna. It was recommended that further work involving the varying of frequency with or without the varying of the value of dielectric constant be done since this one involved a constant frequency of operation with varying values of the dielectric constant, ?r.
