Abstract
This work introduces an innovative method aimed at improving the gain of Dielectric Resonator Antenna (DRA) arrays functioning within the X-band spectrum. The design features a Koch-shaped slot-coupled feeding structure, utilising the properties of a short-ended microstrip line to enhance radiation directionality. The results of the simulation show that compared to conventional rectangular and V-shaped slot designs, the suggested antenna array provides a notable gain enhancement. This performance boost demonstrates how well-suited it is for cutting-edge uses like automobile traffic monitoring and defence tracking systems. It is a very useful option in settings where accuracy and dependability are essential because of its streamlined architecture, which guarantees more efficient signal transmission and reception. All things considered, the antenna’s enhanced features make it a better option for such demanding application situations.
Keywords: Dielectric resonator antenna (DRA), Koch slot, antenna array, X-band, high gain, microstrip feeding, HFSS simulation
