Recent advances in multi-band wireless communication systems have driven the increasing need for dual-band bandpass filters. These types of filters are capable of isolating a small section of the frequency spectrum within a broader spectrum. Over the years, coplanar waveguide, mi…
The rapid advancement of multi-band wireless communication systems has driven demand for compact, high-performance multi-band bandpass filters (BPFs) capable of isolating specific frequency bands within a wider spectrum. This paper reviews the current state-of-the-art in multi-ba…
