Compact dual band slotted triangular monopole antenna for RFID applications

Abstract

This paper presents a compact monopole antenna for radio frequency identification (RFID) systems. The proposed antenna is a dual band structure that can operate in the frequency ranges [0.797–1.004 GHz] and [2.234–2.934 GHz]. Consequently, the antenna covers widely the two UHF bands dedicated for RFID applications which are [0.860–0.960 GHz] and [2.380–2.520 GHz]. Moreover, the antenna is compact and its wide band nature makes it suitable for several applications other than RFID (GSM, UMTS, Wi‐Fi, Bluetooth, etc.). The proposed antenna has been fabricated and its reflection coefficient measured where a good agreement is observed with the simulated results.

Compact dual‐band fractal hexagonal ring monopole antenna for RFID and GSM applications

“…The photograph of the fabricated antenna is shown in Figure . The antenna external dimensions are 61.0 × 41.0 × 1.6 mm 3 which yields a size reduction of about 53% as compared to the structure in the study of Dehmas et al.…”

“…Consequently, only the RFID band is controllable in the one fractal ring configuration. Nevertheless, this antenna, which can operate in the RFID band, realizes a size reduction of about 34% (70 × 50 × 1.6 mm 3 ) as compared to the antenna in the study of Dehmas.…”

“…The design process is based on the work of Dehmas et al in which a slotted triangular monopole antenna suitable for a dual‐band RFID application is developed.…”

Design of Miniaturized Quad-Band Dual-Arm Spiral Patch Antenna for Rfid, Wlan and Wimax Applications

“…It is known that the dominant resonant frequency for most of the antennas is so far dependent on the physical dimension of their radiating elements and subsequently limits the antenna miniaturization to a certain extent. Hence, the design of miniaturized multiband antennas is highly attractive, and persistent attempts for new solutions and approaches are presented by researchers, in particular for antennas operating at lower frequency bands [12][13][14][15][16][17]. In [12], a slotted triangular MA was presented to cover dual bands used for RFID systems and operated in the frequency ranges of (0.797-1.004 GHz) and (2.234-2.934 GHz).…”

A compact coplanar waveguide (CPW)-fed folded SA with overall dimensions of 30×30 mm 2 was proposed in [13] to operate at four bands for 0.94/2.45/5.8-GHz RFID and 2.45/3.5/5.5-GHz WiMAX/WLAN applications.…”
