Enhanced radiation characteristics of regular dodecagon split ring resonator (D-SRR)-based microstrip patch antenna employing dielectric superstrate for THz applications

Abstract In a world where communication requires ever faster data transmission capable of transmitting high speeds. order to reach and transmit this speed, it is necessary increase the frequency that carries information. For this, scientists are interested in terahertz (THz) range which, thanks its frequencies between 0.1 THz 30 THz, offers possibility increasing rate. This letter presents inclusion Dodecagon Split Ring Resonator (D-SRR) rectangular microstrip patch antenna effect performance proposed antenna. The metamaterial design employs two types SRRs resonators shapes such as Broadside Coupled (DBC-SRR) (D-SRR). model applied uses local field approach allowed obtain dispersion characteristics discrete negative magnetic permeability. substrate Arlon AD1000 material, which helps attain gain good directivity at frequency. investigated with without superstrate. operating vary 0.66 - 0.69 shows maximum 10.4 dB 9.84 dB. HFSS software tool simulate parametric analysis design. novel structure may find applications imaging, remote systems manifold possibilities medical field.
