Specific Kind Of Meta-Material Application On High Frequency Structures And Waveguide Antennas

A novel technique was employed to miniaturize the open-ended radiator using electromagnetic meta-materials (MTM). In this paper, an open - ended rectangular waveguide antenna loaded with Back to Back Square Broad Side Coupled Meta-Material Split Resonator (BBSCMM-SR), radiating below the cut-off frequency of the waveguide are designed is proposed. This work has investigated design development, simulation, miniaturization and are comparing with these different types of Ring Resonators of an open end a waveguide dual band antenna. The antenna is capable of radiating below the cutoff frequency of the waveguide by supporting backward waves. Comparing previous work of miniaturization of waveguides, a better bandwidth about 550 MHz, good matching, dual band and low profile antenna is obtained.
