Power dividers and directional couplers are passive devices used frequently in the field of radio technology. In the field of microwave engineering and circuit design, Power Divider is a specific class of power divider circuit that can accomplish isolation between the output ports while maintaining a coordinated condition on all ports. In this paper, the Triangular shaped Micro strip Power Divider is designed for C-band operation using Defected Ground Structure (DGS). The triangular structure of the power divider is introduced to have collinearly output. The passive power divider is used extensively at microwave and millimeter wave frequencies. It supports frequency ranges from 2 to 4.5GHz for better return loss. Phase and amplitude equalizations are used at the output ports to achieve better performance. Calculations are carried out using different simulation tools based on different numerical techniques. © 2018, UK Simulation Society. All rights reserved.
