“…However, the installation of this design is not simple. Furthermore, in order to simplify the fractal antenna design, many researchers proposed a planar fractal antenna printed on microstrip material [15][16][17][18][19]. In [15], Hwang proposed a modified Sierpinski fractal antenna to reduce the antenna dimension and to achieve multiband frequency resonance.…”

“…However, the operating frequency of the proposed antenna is still narrow with a bandwidth of 200 MHz for L-band spectrum. Coplanar-Waveguide (CPW) feeding line is proposed to be combined with Sierpinski based fractal antenna to obtain wideband and compact antenna [17][18][19]. However, the achievable gains of those proposed antenna designs are still low.…”

Abstract-In this paper, a development of compact wideband antenna for L-Band Applications is presented. The proposed antenna is developed based on Modified Sierpinski Based Fractal geometry for the antenna patch with additional meandered structure in the antenna transmission line. The designed antenna is printed on a 10 × 10 cm of substrate with a relative permittivity of 4.3 and thickness of 1.6 mm. The antenna is fed by a 50 Ω microstrip line. The proposed antenna is characterized both in numerical and experimental analysis. The antenna characteristics are analyzed in terms of return loss, bandwidth, antenna gain, radiation pattern and radiation efficiency. From the experimental analysis, the fabricated antenna exhibits reasonable agreement to numerical design. The proposed antenna has an operating frequency from 0.94 GHz to 2.25 GHz with the lowest return loss of −36 dB and maximum gain around 5.49 dBi, as well as radiation efficiency of 97%, approximately.

A novel circularly polarized frequency reconfigurable Koch fractal boundary antenna is proposed. Initially, a Koch slot is etched on the Koch fractal boundary patch of larger dimension (48 × 48 mm2). Within the etched slot, an asymmetrical Koch fractal patch of smaller dimension (36 × 36 mm2) is embedded and switches are introduced along x and y‐directions to connect these inner and outer patch structures. By making ON/OFF switching of the diodes frequency reconfiguration is achieved. Measured results are in close agreement with the simulation results which demonstrates that the proposed antenna is well suited for GSM/Wi‐Fi wireless applications. © 2015 Wiley Periodicals, Inc.

“…Fractal-shaped antennas have already been proved to have some unique characteristics that are linked to the geometrical properties of fractals [1,2]. Additionally, reconfigurable antennas are leading the current antenna research for wireless communication applications [3,4]. The reconfigurable capability enables that single antenna performs equal function with multiple antennas.…”

Fractal patch antennas based on the Sierpinski structure are studied in this paper. The antennas operate at dual bands (around 2 and 5 GHz) and are designed to steer the beam directions at around 5 GHz band (the first harmonic). The antennas use reconfigurable triple feeds on the same antenna plane to have three beam directions. The same scale factor defines the geometrical self-similarity of the Sierpinski fractal. The proposed antennas are fabricated through three iterations from 1st order to 3rd order and utilize FR-4 (εr= 4.4) for the microwave substrate. The performances of the antennas, such as reflection coefficients and radiation patterns are verified by simulation and measurement. The results show that the properties of the proposed antennas in three orders are similar.
