Abstract
This chapter is focused on two different strategies for the design of balanced bandpass filters with common‐mode suppression, where the relevant aspect is the small size of the resulting devices. One of them is based on a combination of open split ring resonators (OSRRs) and open complementary split ring resonators (OCSRRs) and the other one is based on S‐shaped CSRRs (S‐CSRRs). The chapter shows that the combination of OSRRs and OCSRRs is useful to implement compact balanced filters with high common‐mode rejection ratio (CMRR) in the differential‐mode passband. The OSRR and OCSRR are open resonators that can be excited not only by external magnetic or electric fields but also by means of a current or voltage source. The chapter briefly reviews the topology of these resonant elements and justifies their small electrical size, and then details their application to the design of compact balanced filters.
