8th order dielectric resonator filter with three asymmetric transmission zeroes

The dielectric resonator filter is a high-performance filter design which is well-suited for applications where compactness and power are important. These sorts of filters are widely used in communication systems – for example, in mobile phone base-stations. The number of independent design parameters that need to be optimized makes higher-order dielectric resonator filters challenging to tune. Simulation software can therefore be used to make it easier to design and tune these filters.
