Abstract

Microstrip slot array antenna fed by microstrip line is introduced. Slot antenna is designed to operate at 10 GHz for using in radar systems. Antenna have dielectric constant of the substrate is 2.17 (PTFE). In fact, it is study to analyze slot array antenna including feeding line with wide bandwidth. The characteristics of antenna is proposed and analyzed for instance input impedance, $S_{11}$ parameter and far field radiation patterns which these characteristics can also be calculated efficiently and accurately by using FDTD Method.
