“…Miniaturised patches can be shaped and optimised to obtain a large electrical length in limited space using the genetic algorithm [28], running on high-performance computing platforms. Fractal geometries are also used to obtain miniaturised MPAs with good efficiency [5,29]. Fractals are space filling contours in which electrically large features can be effectively packed in a relatively small space, with a reduction in bandwidth.…”

The microstrip patch antenna (MPA) has been in use and has been studied extensively during the past three decades. This antenna, which consists of a metallic patch printed on a dielectric substrate over a ground plane, offers several advantages including ease of design and fabrication; low profile and planar structure; and ease of integration with circuit elements. The minimum dimension of a conventional MPA is in the order of half a wavelength. In recent years, with the advent of new standards and compact wireless devices, there has been a need to reduce the size of this type of antenna. This study discusses some of the principal techniques that have been reported in the literature to reduce the size of an MPA. These miniaturisation techniques include material loading, reshaping the antenna, shorting and folding, introducing slots and defects in the ground plane and the use of metamaterials. The major features and drawbacks of each of these approaches are highlighted in this study along with their effects on the antenna performance metrics.

“…There are many types of fractal geometries such as Koch, Sierpinski, Minkowski, Giuseppe Peano and Snowflake fractal. The resonant frequency of the antenna decreases when the number of the fractal iteration increases [12]. This is due to the increases of the effective length of the patch in a limited volume.…”

This paper reports an investigation on a combination of fractal geometry and half cutting methods in designing a printed monopole antenna for low frequency application. The effects of the combination of fractal shape and partial cutting methods to the printed monopole antenna performances were studied. All designs operate at the Ultra High Frequency (UHF) band. The fractal geometry was proposed in order to shift down the resonant frequency while partial cutting method helps to a further reduction of the overall size of the antenna. Based on the results, it was found that the overall size of the proposed antenna is 53.68 % smaller than the conventional printed monopole antenna at the same resonant frequency. The monopole antenna size is 70.89 x 135.82 x 1.67 mm 3 . It has gain of 2.72 dBi with omnidirectional radiation pattern.

“…With the advent of modern wireless technologies and an ever-growing dependence of our daily life on mobile communication platforms, compact low-cost antennas have gained considerable attention [1][2][3][4][5][6][7][8][9][10][11][12][13][14][15]. Contemporary handheld transceivers, printed phased-array systems, and passive radio-frequency identifications (RFIDs) have imposed stringent requirements on antenna physical sizes, especially those operating at low frequencies.…”

“…Traditionally, printed antenna miniaturization techniques have relied on shortening the length of linear antenna radiators at the expense of the radiators' width and/or height. This have been demonstrated through several concepts, including high permittivity loading materials and elements [1][2][3], photonic band-gap structures [4,5], inverted-F configurations [6,7], folding an antenna radiator into a single-or a multi-layer structure [8][9][10], slots on antenna radiator elements [11,12], fractal geometries [13], and bio-inspired optimization methods to minimize an antenna topology [14,15]. To some extent, miniaturization of printed antennas using loading materials causes the quality factor to increase and therefore decreases the bandwidth, radiation efficiency, and may influence the level of polarization purity [16,17].…”

Abstract-A new miniaturization methodology suitable for printed linear antennas is presented. Miniaturization is accomplished by replacing a linear radiator element of a conventional antenna with a compact continuously varying-impedance profile governed by a truncated Fourier series. A design example of a printed half-wavelength dipole antenna is designed and realized in microstrip technology. The performance of the proposed antenna is compared with its equivalent uniform dipole to highlight the performance equivalency. With a 25% reduction in the dipole arm length, both antennas show a measured peak gain and a fractional bandwidth of 5.4 dBi and 16%, respectively at 2.5 GHz; hence, the overall electrical performance is preserved. It will be shown that the design procedure is systematic and accurate. The proposed approach has potential for achieving advanced frequency characteristics, such as broad-and multi-band antenna responses.
