Design and Analysis of a Photonic Crystal Based Planar Antenna for THz Applications

Modern advancements in wearable smart devices and ultra-high-speed terahertz (THz) communication systems require low cost, profile, highly efficient antenna design with high directionality to address the propagation loss at THz range. For this purpose, a novel shape, gain for frequency range applications is presented work. The proposed based on photonic bandgap (PBG)-based crystal polyimide substrate which gives optimum performance terms of (9.45 dB), directivity (9.99 dBi), satisfactory VSWR (<1) 0.63 THz. studied PBGs different geometrical configurations results are compared homogeneous polyimide-based substrate. effects variations dimensions PBG unit cells also achieve ?10 dB bandwidth 28.97 GHz (0.616 0.64 THz).
