For the first time, a balanced dual‐band bandpass filter using substrate integrated waveguide structure is reported. The co‐shared TE 102 ‐mode cavities arranged on symmetrical plane can greatly reduce common‐mode signal while selectively transmitting differential‐mode (DM) signal. In addition, desired DM response be easily analysed and obtained by equivalent 2‐port circuit model. To validate design concept, one X‐band prototype has been fabricated tested. measured results match well with...
