Abstract
Currently, several microwave filter designs contend for use in wireless communications.
Among various microstrip filter designs, the reconfigurable planar filter presents more advantages
and better prospects for communication applications, being compact in size, light-weight and
cost-effective. Tuneable microwave filters can reduce the number of switches between electronic
components. This paper presents a review of recent reconfigurable microwave filter designs,
specifically on current advances in tuneable filters that involve high-quality factor resonator filters to
control frequency, bandwidth and selectivity. The most important materials required for this field
are also highlighted and surveyed. In addition, the main references for several types of tuneable
microstrip filters are reported, especially related to new design technologies. Topics surveyed include
microwave and millimetre wave designs for 4G and 5G applications, which use varactors and
MEMSs technologies.
