Abstract

Radio Frequency Identification (RFID) is one of the implementations under auto identification (AUID) technique. It is basically used in identification of items, animals, books etc. The patch antenna is a trendy resonant antenna for narrow-band microwave wireless link applications such as RFID systems. In this paper a rectangular micro-strip patch antenna is designed and thoroughly analysed. Taking into consideration different antenna parameters like directivity, bandwidth, and gain etc., an improved version from the simple rectangular patch has been developed by introducing a bi-anisotropic omega shaped metamaterial within the patch, also known as reciprocal metamaterial. The results obtained after simulation in High Frequency Structure Simulator (HFSS) were so much effective with the considerable enhancement in the values of directivity, bandwidth. Modelling of this omega shaped patch antenna has revealed results that are suitable for RFID antenna design.
