“…Compact sized HFA using Koch and self-affine geometries have been analyzed and investigated for the wideband frequency range applications. 89 The proposed antenna structure was the combination of Koch curve and self-affine fractal geometries. Proposed HFA has been fabricated and its experimental results were also being juxtaposed with simulated results for anticipating the novelty of design.…”

The comprehensive review of hybrid fractal antenna (HFA) has been presented in this article. Distinguished researchers have designed, analyzed, and investigated numerous types of HFA's as per the requirement of the market. Firstly, it gives introduction about the fractal antennas (FAs) along with the need of integration of the fractal geometries then research motivation. The extensive literature survey has been divided into three different parts as, fusion of same type of fractal geometries, amalgamation of two distinct fractal geometries and concoction of three different fractal geometries, further, the comparative analysis among these HFA's has been made on the basis of their size, geometries used for designing, number of resonant frequency bands, gain, bandwidth, radiation efficiency, circular polarization, and their applications. The juxtaposition among different HFA's has also been delineated in tabular form for more limpidity along with the findings of individual research article. The challenges faced by researchers while designing the antennas are also being portrayed in this article. This review may be supportive for the novices to carry out their research on HFA as such type of comparative analysis on HFA's is not existing in the open state of art literature as per best of authors knowledge.

SummaryThis article investigates a compact π‐shaped circularly polarized Minkowski fractal antenna (MFA). The proposed radiator is taking a π‐shape with semicircular cuts along the opposite side of the patch with a V‐cut at the bottom. A second‐order Minkowski fractal curve is implemented on the bottom ground plane. The antenna element is powered by a coaxial probe. The asymmetric structure generates two orthogonal modes, which results in circular polarization. A maximum gain response of 7.1 dBic is observed in the impedance band width (IBW) covering 9.7 to 11.2 GHz. The patch is fabricated on substrate RT/Duroid 5880™ (𝜀𝑟=2.2). The antenna has a compact dimension of 0.90λ0 × 0.90λ0 × 0.05λ0 (fr = 10.45 GHz). A good match in the results validates the simulated and measured data in comparison with the existing models from literature with respect to diversity performance, thus making it suitable for radar applications.

“…The interest in the design of fractal antennas [9–14] has been continuously increasing since the past few years as they are a very good substitute for the large-sized antennas [15, 16]. They have a very good ratio of electrical size to physical size compared to the traditional antennas.…”

An inscribed hexagonal fractal slotted patch antenna with some additional geometry and slots is proposed for the optimization in this paper. This research work is concerned with the optimization of this slotted fractal antenna with the help of the curve-fitting method in conjunction with the modified version of Lightning Attachment Procedure Optimization (MLAPO) technique. The data required for the curve-fitting technique and for the optimization technique have been obtained by varying some of the parameters of the proposed antenna. Different equations are developed to know the relations between these parameters of the proposed antenna. The MLAPO technique is applied thereafter to calculate the different optimized geometrical parameters to optimize the bandwidth for the proposed antenna. The optimized geometrical parameters are verified with the help of a parametric variation to justify the reliable optimization. The bandwidth obtained by the MLAPO technique has been found to be better than that obtained by PSO and normal LAPO algorithm. The prototype of the optimized antenna is fabricated and the experimental results are found to be compatible with the results obtained by simulation. The proposed optimized antenna may be utilized in various applications in C and X bands.
