Design of an S-Band Rectangular Microstrip Patch Antenna

Adejoh Joshua, Okere B. I., Lanre Danian

An S-band antenna is to operate within the frequency range of 2-4 GHz. This frequency is designed to operate at the frequency of 2.2 GHz using the dielectric substrate, FR4dielectric material of dielectric constant of 2.6. The design employed the transmission line model and parameters of the rectangular microstrip patch antenna were obtained using Microsoft excel worksheet. The result shows that the antenna has the length of 40.23 mm, width of 50.82 mm and the high of the substrate as 4.04 mm. Also, the substrate has the length or Ground plane length, Lg, of 64.45 mm and Ground plane width, Wg, of 75.04mm. From this design dimensions, the antenna can be used for devices that have limited space for antenna, or its communication unit.
