Miniaturization of Waveguides Dual Band Antenna Using TSRR-WS Metamatrerials

M. Jalali, T. Sedghi and Y. Zehforoosh

Abstract—In this paper, an open - ended rectangular waveguide antenna loaded with Triangular Split Ring Resonators and Wire Strip (TSRR-WS) radiating below the cut-off frequency of the waveguide is proposed. This work has investigated design development, simulation and miniaturization of an open end a waveguide dual band antenna. A novel technique was employed to miniaturize the open-ended radiator using electromagnetic metamaterials (MTM). 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 600 MHz, good matching and low profile (with 5 unit cell of MTMs) antenna is obtained.
