Matching network design of microstrip antennas with simplified real frequency technique
Abstract
The use of the simplified real frequency (SRFT) for the design of matching networks of microstrip antennas to increase bandwidth is presented. By using the SRFT, there is no need to determine any form of equivalent circuits or analytical impedance functions for the antennas and generators; the real frequency or experimental data of the antennas and generators are processed directly. Also, there is no need to choose an algebraic transfer function as a measure of performance and it is not necessary to assume the topologies of the matching networks in advance. The final result is an optimized physically realizable real normalized reflection coefficient that describes the matching network. The matching networks are generally simpler and give superior gain properties that structures obtained by the analytic procedure.
