Nano-sized Slotted Microstrip Patch Antenna for X Band Operation

Recent researches have extensively explored patch antenna design for deriving better performance for operation in X band. One of the novel techniques in slotted microstrip patch antenna design is to cut nano-sized slots over the substrate of the patch. Nanostructures are expected to provide unique characteristics and can possibly help in performance improvement of the patch antenna. This paper focuses on the study and design of a rectangular slotted microstrip patch antenna in High Frequency Structural Simulator (HFSS) simulation software for X band operation. The antenna is designed over an RT Duroid 5880 substrate with 100nm×100nm dimension square slots over its surface. The square slots are arranged in five different forms and their performances are compared. The results show that there is an improvement in the return loss with an increasing number of slots.
