TABLE 1. OPTIMISED DIMENSIONS OF THE PROPOSED ANTENNA
Fig.  5  illustrates  the  proposed  antenna  with  and  without  the  CDR.  When  the  structure  does  not  contain the CDR, the antenna works from 5 to 12 GHz with 82% impedance bandwidth for reflection  coefficients<  –10  dB
TABLE 2. SIMULATIONS AGAINST THEORETICAL PREDICTION OF BAND-NOTCHED ANTENNA
Fig. 6 shows the current distribution at the centre notched band. The dimension of the slot L s = 9mm  [determined by formula (1)] corresponds to the notched band WIMAX
