Abstract :
FEM analysis has been used to optimize various microstrip line sections used for designing PIN-Diode ?? attenuator used for phased array antenna applications. Results have been compared with the theoretical results obtained from closed form analysis expressions of microstrip line. An error of only 0.92% has been observed between the two results at 50?? characteristic impedance for unshielded microstrip line.
