Abstract
Recent advancement of communication system requires low cost, minimal weight, low profile and high-performance antenna to execute the demand of the future realization. A high gain novel microstrip patch antenna design is proposed, based on the photonic crystal for terahertz (THz) spectral band applications. This antenna is mounted on polyimide substrate that employs Photonic Band Gap (PBG) crystal and the Gain of 7.934â¯dB, Directivity 8.612 dBi and VSWR close to unity at resonant frequency of 0.6308â¯THz. The proposed antenna model is compared with homogeneous polyimide substrate structure based microstrip patch antenna and analyzed the radiation characteristics. Moreover, the performance of designed antenna is investigated with different PBG cylindrical distance, PBG hole radius, curvature radius of patch and substrate heights. The projected design antenna has a bandwidth of 36.25â¯GHz and â10â¯dB impedance with operating frequency range varying from 0.6152â¯THz to 0.6514â¯THz, hence it can be utilized for detection of explosive and material characterization applications.
