The aim of this work was to design a rectangular microstrip patch antenna that will be used for signal transmission and/or reception at the frequency of 22 GHz. The design was done using five different values of a dielectric constant, ?r; 3.1, 3.2, 3.3, 3.4, 3.5, respectively. The results showfive different antennas with different heights, width, length, and the feed distances, or havingdifferent dimensions were designed from change in the values of the dielectric constants of the substrate at the same frequency of 22 GHz. It was concluded that at constant frequency, the height, width, length and the feed distances of a rectangular microstrip patch antenna is inversely proportional to the value of the dielectric constant of the substrate, and it can be seen in; at the ?r of 3.2 value, the length of the patch, L, is 3.75 mm, the width, W, 4.70 mm, the height, h, is 0.364 mm, the ground length, Lg, is 5.94 mm, the ground width, Wg, is 6.89 mm, the feed distance along X-axis, Xf is 1.10 mm, the feed distance along Y-axis, Yf is 2.35 mm, and at the ?r of 3.5 value, the length of the patch, L, is 3.59 mm, the width, W, is 4.55 mm, the height, h, is 0.348 mm, the ground length, Lg, is 5.68 mm, the ground width, Wg, is 6.63 mm, the feed distance along X-axis, Xf is 1.01 mm, the feed distance along Y-axis, Yf is 2.27 mm. Future work was recommended on how the varying values of a dielectric constant affects the dimension of other types of patch antenna like the circular one.
