Micrsostrip antennas are mainly used for high frequency signal transmissions and/or receptions in order that the antenna will be small in size. The aim of this work is to design an antenna that can be used in small-sized devices such as mobile phones, radios, wireless computers and which will operate at the frequency of 4.5 GHz.The dielectric substrate, RT DUROID 5888 of dielectric constant 2.6 was used for the design, and the dimension of the antenna was obtained using analytical (mathematical) processes as height of 1.97 mm, width of 24.85 mm and length of 19.7 mm. This was done using transmission line method of microstrip patch antenna design. The feed point location (Xf, Yf) was found along the point along the X-Y coordinates where the impedance is nearly 50O to be 6.4 mm and 12.43 mm respectively. The points were found using coaxial feed method.
