The microwave absorber is important in various applications and metamaterial shapes are noticed for multiband application. In this paper, we have developed a microwave absorber based on the broken cross with Jerusalem load for multiband application and in addition the prototype structure shows polarization independence for 0° to 60° incident wave angle. In this article, we have proposed and analyzed a microwave absorber based on the fractal broken cross with Jerusalem load in unit cells for multiband applications. This absorber is simulated with CST by FIT numerical method with periodic boundary condition and prototype structure have fabricated over FR‐4 low cost substrate for dual band application and test in the chamber room. We have done parametric studies about the arms and parasitic elements on absorption manner and resonances. The current distribution shows that how the symmetrical shape is made uniform distribution and made independent of the incident wave polarization. As a result, the designed MA is useful for microwave application in medical imaging and communication systems.
