Abstract :This study presents a design of coax-fed rectangular microstrip antenna operation in different applications within the context of X-bands. High gain and radiation pattern characteristics are obtained by using coaxfed network technique. The Rogers Kappa was chosen as a substrate material for the designed patch antenna with a dielectric constant of 4.38, and a height of 2.4 mm. Simulation results are obtained and examined by using the High Frequency Structure Simulator insert ignore into journalissuearticles values(HFSS); software. The simulated results indicate the band from 8.2GHz to 11.7 GHz insert ignore into journalissuearticles values(return loss < −10 dB); and produce a gain of 6.53 dB at 8.7GHz and 11.65 dB at 11GHz, respectively
