“…However, printed and microstrip patch antenna structures have been also reported in the literature to design compact dual-band and multiband for multifunctional communication services [15][16][17]. Furthermore, antenna structure based on Cantor fractal geometry and its variants have been attractive to antenna designers to produce compact and ultrawideband, multiband and dual-band antennas for a wide variety of communication applications [18][19][20][21][22][23][24][25][26][27]. It is worth to note here that most of the applications of Cantor fractal geometries are in the design of antennas for wideband and ultrawideband applications [18][19][20][21].Printed slot antennas based on square Cantor fractal geometries have been reported in [22][23] to design a dual-band antenna for 2.5/ 5.8 GHz WLAN applications.…”

Cantor fractal geometry and its variants are found attractive for microwave antenna designers seeking for compact size multiband antennas. This paper presents the design of a new microstrip fed printed monopole antenna for use in dual-band wireless applications. The radiating element of the monopole antenna is in the form of Cantor fractal geometry of the second iteration as applied on rectangular patch. The monopole radiating element has been etched on a substrate with relative permittivity of 4.4 and 1.6 mm thickness and is fed with a 50 ohm microstrip line. A reduced ground plane has been etched on the reverse side of the substrate. Modeling and performance evaluation of the proposed antenna have been carried out using the commercially available EM simulator, IE3D. Simulation results reveal that the proposed antenna offers dual-band resonant behavior with -10 dB impedance bandwidths and radiation characteristics suitable for almost most of the recently available services in the 1-6 GHz range. A parametric study has been carried out to explore the effect the aspect ratio of the proposed antenna radiating element on its performance. The study reveals that the radiating element aspect ratio has a considerable effect on the coupling of the two resonant bands. Besides the simple design, the antenna offers reasonable radiation characteristics. Simulated-10 dB impedance bandwidths for the lower and the upper resonant bands are (2.30-2.84 GHz) and (5.56-6.01 GHz) respectively. This makes the proposed antenna suitable to cover numbers of operating bands of the wireless communication systems (2.4 GHz-Bluetooth, 2.4 GHz ISM, 2.5/5.8 GHz-WLAN, 5.8 GHz-ITS).

“…Even though several wideband antennas have been designed to cover all the WLAN/WiMAX bands , the multiband antennas are more preferred. Most of the existing compact antennas proposed for wireless applications support either WLAN or WiMAX standards . However, these antennas still have large size, inability to cover all the wireless bands, insufficient bandwidth and are incompact for modern wireless communication devices.…”

A novel multiband loaded trapezoidal ring fractal antenna (TRFA) is proposed for wireless local area network (WLAN) and worldwide interoperability for microwave access (WiMAX) applications. The self‐similarity property is applied to the trapezoidal structure and the fractal geometry is achieved by consecutive iterations. The proposed antenna has a compact size of 30 × 30 × 1.6 mm3. The antenna is fabricated and tested. The fourth iteration of the proposed TRFA covers the 2.4/5.2/5.8 GHz WLAN bands and 2.5/3.5/5.5 GHz WiMAX bands with uniform radiation characteristics and an average gain of 2.20 dBi. © 2014 Wiley Periodicals, Inc.

ABSTRACT:Microstrip antennas find applications in aircraft, satellite and missile applications where important characteristics are size, weight and complexity. Design and simulation has been carried out using IE3D simulation software. Minkowski fractal geometry has been applied on patch of antenna to form self similar H-shaped patch antenna. By applying DGS in horizontal direction and vertical direction, characteristics of antenna are observed. When DGS has been changed in horizontal direction and Fr-4 has been used as substrate then antenna resonated at 2.7 GHz, 4.8 GHz and 6.2 GHz with return loss of -17.66 dB, -13.6 dB and -23.66 dB. This antenna has gain of 6.05 dBi, 5.6 dBi and 3.66 dBi. Results are also obtained for H-shaped fractal patch antenna by applying plus shaped DGS and slot shaped DGS, hence antenna can be used for WLAN applications. When microstrip feed line has been used, proposed antenna can be useful for GPS application.
