Rectangular Ring Antenna for Wearable System

Abstract

This paper performs an investigation of Radio Frequency Identification (RFID) antenna design for wearable systems. A microwave wideband dual rectangular ring antenna is selected for the further consideration. The basic concepts and structure of wearable systems and RFID antennas are discussed first, followed by an introduction to the basic structure and design parameters of a dual rectangular ring antenna. Lastly, the tri-rectangular ring antenna is introduced. Through optimization, the operating frequency band of the antenna is successfully increased.
