A new design of electromagnetic band gap (EBG) waveguide low‐pass filter (LPF) loaded with double‐array is described to improve the stopband characteristics. Broader gapband width, about 2‐GHz broader than the traditional filters, greater stopband attenuation, and moderate passband insert loss (0.5 dB) can be obtained. Theoretical and measured results are in good agreement. The filter can be employed for the out‐of‐passband clutter rejection of traditional filters. © 2008 Wiley Periodicals, Inc.
