“…Fractal-shaped antennas is another common technique to introduce multiple bands and reduce the size of the antenna. In [10], a new modified antenna by semi-fractal technique has been used for multiband RFID reader applications at 3.8, 5.8, 8.2, and 9.7 GHz frequencies. A star-shaped fractal antenna has also been used to cover commercial and military applications [11].…”

Abstract-This paper presents a novel miniaturized dual-band fractal antenna for WLAN/WiMAX applications. The miniaturization of the proposed antenna is achieved by inserting, in the center ground of the antenna, square slots to excite two resonant modes simultaneously, leading to dual-band operation. The novelty of the proposed antenna is miniaturized size and ability to support multiband operations, which can be integrated in many electronic applications and wireless communication. This antenna has a compact size of only 25 × 25 mm 2 and fed by a 50 Ω-microstrip feed line. To validate the design approach, an experimental prototype is fabricated and measured. The simulation and measurement results show that the antenna provides dual-band operation at 2.4 and 3.75 GHz with omnidirectional radiation pattern.

This paper presents the design, fabrication, and measurement of a novel ultra‐wideband (UWB) fractal monopole antenna. This antenna uses trapezoidal shapes with hexagonal slots to achieve highly Ultra‐Wideband characteristics. The antenna is practically fabricated and tested. Measured results show a good agreement with simulated results and demonstrate that the proposed fractal antenna provides an ultra bandwidth of about 126% ranging from 3.1 to 13.67 GHz for the reflection coefficient less than −10 dB, outperforming the basic hexagonal design. This impedance performance makes the antenna suitable for C, X, K band applications. © 2016 Wiley Periodicals, Inc. Microwave Opt Technol Lett 58:2370–2374, 2016

SummaryIn this research work, the design and analysis of a compact microstrip antenna having a monopole structure with 64.86% of wide bandwidth is presented. The main radiator of the structure is a fractal‐based geometry with the shape of a half‐Koch snowflake, and the ground plane is partial (defected ground). The design methodology of the antenna is presented using analytical modeling, and the structure prototype is fabricated to verify the performance. Measurement outcomes confirm the −10 dB bandwidth in range of 4–7.84 GHz, thus covering approximately the C‐band with omnidirectional radiation patterns. The proposed antenna shows a peak realized gain of 3.4 dBi at 7.2 GHz and has an overall dimension of 0.33λ × 0.49λ × 0.03λ, at 5.8 GHz. The structure is found compact compared to some recently reported designs and the read range is found to be 1.98 cm at 5.8 GHz. The read range and validation of the propagation test indicate the suitability of the compact and wideband planar antenna in various short‐range reader applications.
