Design and evaluation of an elliptical patch textile antenna for RFID application and bending consequences

This paper presents a design of an elliptical patch textile antenna having operating frequency at 2.45 GHz for RFID application. The proposed antenna consists of elliptical patch on Dacron fabric (□_r=3) as substrate followed by a partial ground at the back of the substrate. The overall size of the proposed antenna is 45×38 mm². The proposed antenna has a gain of 3.386 dB with VSWR of 1.07. The performance of the proposed antenna is analyzed under four angles of bending. The effect of change in feed length is also focused. The characteristics, low profile and compact size of the antenna depicts as a potential candidate for RFID application. CST Microwave Studio package is used for design and simulation purpose.
