Modified Rectangular Planar Antenna with Stubs and Defected Ground Structure for THz applications

Abstract The paper presents the design and analysis of wideband planar antenna having dual stub with defected ground structure for terahertz applications. The designed antenna is fed by microstrip line feed and provides an impedance bandwidth of 7.47 THz (0.53–8 THz). To obtain the optimum performance, the parametric analysis on design is carried out. A maximum gain of 16.48 dB has been acquired by an antenna at 5.963 THz.
