In this paper, we investigate an aperture-stacked patch microstrip antenna with three slots in a circular shape that feeds the antenna in order to have an improvement in its performance. The structure optimized and analyzed in this study has an upper substrate of foam dielectric material with a thickness of 0.254 mm and a dielectric constant of 1, a lower substrate of rogers RT3003 with a thickness of 0.5 mm and a loss tangent of 0.001. A cost-effective technique of improving the front-to-back ratio used in this work is to install a reflector which take shape like an aperture-stacked, printed on a thin dielectric layer (0.254 mm) with a dielectric constant of 4.4 and a loss tangent of 0.025. As a result of using the proposed reflector to increase the directivity, the front-to-back ratio of the proposed antenna improved by about 10 dB. With 7.79 dB and matching S11 -40 dB, the structure provides an intriguing gain value.
