The results obtained through CST MICROWAVE STUDIO design software and are very. ![]() Microwave Opt Technol Lett 48: 1522–1525, 2006 Published online in Wiley InterScience (DOI 10.1002/mop. And another Metamaterial antenna using three unit cells gives a better gain of 5.197 dB, overall efficiency of 92.5 and a return loss of -13.5 dB at 5 GHz frequency and the gain, efficiency and return loss are 4.183 dB, 60.78, -14.5 respectively for 2.4 GHz. The natural stopband of the substrate is used to enhance the total bandwidth of a quarter‐wave stub stopband filter. The challenging tasks of designing and simulating the matematerial are carried out using CST Microwave studio 2010. To calculate the complex values of permittivity and permeability Nicolson-Ross-Weir (NRW) approach is used with the help of MATLAB. The effective parameters retrieved for the split‐ring resonator unit cell show that the stopband in the microstrip measurement corresponds to the region of negative permeability of the substrate. Experimental operation of a high power microwave source with a metamaterial (MTM) structure is reported at power levels to 2.9 MW at 2.4 GHz in full 1 s pulses.The MTM structure is formed by a waveguide that is below cutoff for TM modes. metamaterial structure is designed on low cost FR4 substrate. Transmission measurements show that the substrate acts as a natural stopband filter. ![]() Wu, Bae‐Ian Kong, Jin AuĪ left‐handed metamaterial consisting of split‐ring resonators is constructed and used as a substrate for a microstrip line.
