In this paper a sharp compact stopband filter is introduced based on unbalanced dual composite right left handed D-CRLH unit cell. The designed stop band can be used to suppress any undesired signals in WLAN frequencies. The filter works for applications in C-band, where the allocation receiving frequency of the standard C-band. The cutoff frequencies of the proposed filter are 3 GHz and 5 GHz. Moreover, the proposed filter has a very sharp stopband response. The filter size is only 0.329 ? g � 0.609? g where ? g is the guided wavelength at 4 GHz. � 2018 IEEE.
