“…The published reviews provide a fairly comprehensive overview of fractal antennas designing research . These studies can be divided into two categories: the first deals with the study of fractal antenna elements (examples of microstrip antennas studies) and the second, deals with use of fractals in antenna arrays design (examples of fractal antenna arrays studies).…”

“…In contrast to the traditional definition of a Gosper curve, this new Gosper curve is called a node-Gosper curve [2,3]. Originally, the Gosper curve was mainly applied in the design of communication antennas, as in [7,8], and occasionally in visual image processing, as in [9]. Recently, the node-Gosper curve has been successfully applied to solve the mobile anchor localization problems of WSNs [3].…”

Because of recent advances in wireless power transfer technologies, several key topics of wireless sensor networks (WSNs) need to be revisited. Traditional data collection methods for WSNs typically consider the balance of power consumption among sensors as a critical design criterion for avoiding uneven power depletion in the networks. I propose a solution for the uneven power consumption problem of data collection over WSNs. I designed a node-Gosper island-based scalable hierarchical cluster transmission method in conjunction with a wireless recharge plan for data collection over rechargeable WSNs. For the recharge plan, I used mobile wireless chargers to visit and recharge the batteries of sensors located on different levels of node-Gosper curves with various frequencies. The duration of each recharging process for each layer of sensors was calculated to verify the feasibility of the proposed recharge plan. The simulation results indicate that my proposed data collection method outperforms several wellknown data collection methods in terms of energy consumption and that my proposed recharge plan is more efficient than previous approaches in terms of charge path length, number of alive nodes, and traveling efficiency.

“…They have been proven efficient to finding the proper excitations or the suitable division of the arrays in sub-arrays in order the antenna to produce a desired radiation pattern with respect to the SLL and the directions of the nulls or to optimize the antenna by broadening the frequency bandwidth [11,[15][16][17][33][34][35]. GAs have also been used to thin an array [18], in combination with Particle Swarm Optimization Technique to modify sparse arrays [21] or to modify fractal arrays [29,36]. In all cases the target was the achievement of special performance features.…”

Abstract-A novel fractal antenna-array type is proposed. The design is based on the Sierpinski rectangular carpet concept. However, the generator is a circular ring area, filled with radiating elements, so the higher stages of the fractal development produce large arrays of circular rings which, besides the high directivity, have the advantage of the almost uniform azimuthal radiation pattern, attribute that many applications require. The introduced arrays can operate as direct radiating multi-beam phased arrays and meet the requirements of satellite communications links: high End of Coverage (EOC) directivity, low Side Lobe Level (SLL) and high Career to Interference ratio (C/I). These operational indices were further optimized by a synthesized multi-objective and multi-dimensional Genetic Algorithm (GA) which, additionally, gave arrays no more than 120 elements.
