Compact bandstop half-mode substrate integrated waveguide filter based on a broadside-coupled open split-ring resonator
A shunt RLC resonant circuit obtained from a broadside coupled open split ring resonator (BC-OSRR) is proposed. This BC-OSRR cell allows a parallel connection with planar waveguides. Hence, it has been applied to a halfmode substrate integrated waveguide (HMSIW) section. The analysis of the frequenc...

| Resumo: | A shunt RLC resonant circuit obtained from a broadside coupled open split ring resonator (BC-OSRR) is proposed. This BC-OSRR cell allows a parallel connection with planar waveguides. Hence, it has been applied to a halfmode substrate integrated waveguide (HMSIW) section. The analysis of the frequency response and electromagnetic field distribution of the HMSIW structure loaded with an appropriate BC-OSRR cell have shown two main behaviors. The first characteristic is a high-pass frequency response inherent to the HMSIW and the second is a transmission zero in the pass-band of the HMSIW, which is due to the resonance of the BC-OSRR cell. First- and second-order prototypes have been designed and fabricated. The measured band-stop HMSIW filters using BC-OSRR achieve a 3 dB stop-band bandwidth around 10% with more than 21 dB insertion loss. This BC-OSRR cell with low undesired radiation loss can be a new alternative for the implementation of compact band-stop filters in planar technology |
