A Novel Small Sierpenski Antennas

This paper presents the development of a new miniaturized and compact GCPW-fed slotted rectangular antenna structure reader for wideband UHF RFID applications. The optimized proposed antenna is suitable to operate a large frequency-band range from 0.8GHz to 1.3GHz with a bandwidth of 500MHz with a return loss less than -10dB. The antenna is based on a 1.6mm thickness FR4 epoxy substrate with a reduce dimensions compared to the simple rectangular antenna and size of proposed antenna is 47*40mm2. The new design consists of a compact rectangular patch with symmetric U-shaped slots and I-shaped include a partial ground plan and fed by 50 Grounded coplanar line. The antenna parameters have been investigated and optimized by using CST Microwave Studio. To validate the CST Microwave Studio results before the antenna achievement, we have conducted another study by using ADS. The final circuit achieved, measured and validated. Experimental results show that the proposed antenna has good radiation characteristics and operating in UHF-RFID applications.

“…The component that plays a vital role in the RFID system is RFID tag which is composed of an antenna and a chip. In designing the RFID tag, the size of the antenna and the sensitivity of the tag to the object it is attached to need to be considered [2] [3]. The tag will be mounted on the objects with different kind of materials including metal.…”

A microstrip dipole UHF-RFID tag antenna that can be mounted on metal object is presented in this paper. The antenna, which has a very simple structure without any shorting pin and shorting plate, is composed of ladder feed line, rectangular loop, capacitive tip-loading and T-match structure. The insertion of ground plane in the tag antenna design reduces the negative impact of metal object to the performance of the tag antenna. The tag is designed to operate in the Malaysia frequency range with the center frequency of 921 MHz. The performance of the tag is evaluated through simulation and measurement in terms of impedance matching, antenna reflection coefficient and tag reading range. The measured reading range obtained when the tag is in free air and on metal object is 2.3 m and 2.2 m respectively.

“…The rapid growth of wireless internet for high data rate communication has fostered tremendous attention towards the design of compact WLAN antennas. Different types of designs catering to various user requirements have been reported in literature [1][2][3][4][5][6][7][8][9][10][11]. These designs, however, have complex structures which make them difficult to integrate with WLAN systems.…”

“…In literatures [10,11] proposed a fractal antenna for RFID applications, these designs also need rigorous itration to achive the diserd band of resonance. Hence In this article, a planar ACS fed configuration obtained by removing the ground plane at the left of CPW fed antenna which produce a dual band resonance.…”

A compact planar antenna for dual band applications is presented in this paper. The proposed antenna has Dumbbell shaped defect on the ground plane and it is fed by Asymmetric coplanar strip(ACS). The antenna is printed on FR4 epoxy substrate and it has a compact size of 21× 19 × 1.6 mm3. The antenna exhibits a dual band of resonances at 3.4GHz and 5.5 GHz which is used for WiMAX/WLAN. The planar design, simple feeding techniques and compactness make it easy for the integration of the antenna into circuit boards. Details of the antenna design and simulated results are presented and discussed. Simulation tool, based on the method of moments (Mentor Graphics IE3D version 15.10) has been used to analyze and optimize the antenna. Various features such as compactness, simple con-figuration and low fabrication cost make the antenna is suitable for dual band wireless applications.
