“…Fractal shapes usually consist of copies of themselves but with different scales, and have no specific size. Among various types of fractal geometries, the most common ones employed in antenna design includes Sierpinski carpet [5,6], Sierpinski Gasket [7], Minkowski loop [8] and Koch curve [9]. Compact circularly polarized rectenna with unbalanced circular slots was proposed by Y.O et al 12% size reduction was achieved by reducing the radius of rectenna from 16.5 mm to 15.5 mm [10].…”

This paper presented a modified edge fed Sierpinski carpet microstrip patch antenna for antenna miniaturization. The proposed design was etched as Sierpinski carpet to lower the antenna resonant frequency, which is used to reduce the conventional patch antenna size. After the Sierpinski carpet second iteration, the proposed antenna was modified by replacing the rectangular slot in the middle of the patch with a circular slot. Simulation results showed that the proposed antenna achieved 46.5% size reduction when compared with the main patch antenna without affecting the resonant frequency and radiation patterns.

“…36.5% size reduction was achieved after the second iteration of Sierpinski carpet fractal. The present design shows more percentage size reduction when compared with the proposed design in [4][5][6][7][8][9][10][11][12][13][14][15] using Sierpinski carpet fractal iterations.…”

“…These techniques to design multifrequency microstrip patch antennas are based on using several radiators [6,7], fractal-based geometries [8], stubs [9,10] and coupled resonators [11]. Recently, the authors have proposed the use of single-layer microstrip patch antennas partially filled with Composite Rigth/Left-Handed (CRLH) structures to increase the capabilities of these popular radiators.…”

Abstract-In this paper, a novel technique to develop multifrequency microstrip patch antennas with polarization diversity or circular polarization is presented. The proposed approach consists of exciting modes with orthogonal polarizations in microstrip patches partially filled with Composite Right/Left-Handed (CRLH) cells. Two different kinds of quad-frequency single-layer patch antennas are proposed. The first one has two orthogonal ports with high isolation between them. The second kind of quad-frequency patch antennas consists of exciting the four modes with two orthogonal polarizations through only one port. Finally, the proposed approach is used to develop dual-frequency circularly-polarized (CP) patch antennas by exciting the modes with orthogonal polarizations in quadrature phase. Prototypes of all the designs are manufactured and measured, showing good performance.

“…realized by the antenna engineers and researchers to create new and effective triangular microstrip patch designs, with compact size and high-directivity based on the Sierpinski fractal presented in [2] and a dual-frequency antenna based on the Sierpinski fractal with two parasitic patches to enhance the impedance bandwidth, reported by [3]. The use of a single patch antenna is often insufficient to meet the imposed radiation constraints.…”
