Suspended strip‐line (SSL) filter is of wide application values for its low insertion loss, high quality factor value, easy integration and compact size. In this letter, we proposed the design of a dual‐band SSL band‐pass filter based on electric metamaterials, which is realized by introducing a rejection band inside the wide pass‐band of a conventional SSL filter. The electric metamaterial can produce negative permittivity and thus hinders the transmission of EM waves along the strip‐line. To verify the design method, a prototype, together with a conventional SSL filter for comparison, was designed, fabricated and measured. Both the simulation and experiment results verify the dual‐band band‐pass filtering property.
