Present and upcoming technology tendencies in wireless communication must increase the request for microstrip antennas that can effort at many bands with appropriate bandwidth . Microstrip antennas are one of the elementary components vital for wireless communication. This paper includes the design of a microstrip antenna with a total size of (85.3 × 80.3 × 1.6)mm3 using CST2019 software. The antenna was printed using a FR-4 (epoxy) substrate with dielectric constant of 4.3, and the simulation results were compared with the experimental results. The radiation characteristics of the antenna were improved using a set of procedures to obtain the dual-band antenna with a working frequency of the first 1.2GHz suitable for GPS applications with a return loss of -37.55 dB and a VSWR of 1.0279 dB with a gain value of 2.96 dB. The second frequency, 2.4745 GHz, suitable for WLAN applications, has a return loss of -32.69 dB, a VSWR of 1.049 dB, and a gain value of 3 dB. The antennas are fed with a bar line technique.
