RECONFIGURABLE MICROWAVE BANDSTOP FILTER USING NOVEL STEPPED IMPEDANCE RESONATOR

The exponential growth of modern wireless communications market creates an unprecedented
demand for compact-size. low-cost. high-performance and reconfigurable filter.
Due to this recent development. much attention has been devoted to compact microwave
reconfigurable filters. The first condition that must he met by a reconfigurable filter is
that it must he capable of inducing microwave transmitters and receivers to he adaptable
to multi-hand operations using a single filter. which is highly desirable in the current
wireless communication technology.
