“…For tracking large moving objects, patch antennas with array configuration are used as well as parabolic dish antennas. However, it is difficult to obtain high gain with patch antennas [15][16][17]. The primary reason for using helical antennas in satellite communication is that they can be designed with circular polarization and provide high gain [11].…”

High-power wide band helical antenna is designed, analyzed and manufactured in the Electrical and Electronics Engineering Department Laboratory of the Faculty of Engineering of Karabuk University. Krauss's formulas are used in the design of the proposed antenna and Ansys HFSS program is used to simulate it. After the antenna is designed, its dimensions are optimized and analyzed. Thus, the desired antenna parameters were obtained. To maximize performance and match the input impedance to that of the antenna, the diameter of the winding wire has been increased, resulting in a lower VSWR and a much greater operational bandwidth. The proposed antenna has 4.5 turns, a wavelength of 51.72 mm, a height of 58.05 mm, spacing of 12.9 mm, and a diameter of 16.1 mm. This antenna resonates at the 5.8 GHz center frequency and has a bandwidth of 2.92 GHz. The bandwidth is 50.34% of the center frequency value. The presented antenna on Teflon substrate has achieved a gain of 12.06 dB. The proposed antenna also can be used for various wireless applications such as wideband, 5G and drone applications.

“…Material distribution has a great impact on the mechanical properties of mechanical structures. As an effective design tool, topology optimization aims to seek the optimal material distribution for given objective function and constraints in a pre-set design domain, which can improve mechanical properties [1], [2].There are many modelling methods to be presented, including variable density method [3], [4], level set method [5]- [7], and evolutionary structural optimization method [8]- [10]. The solution method is generally divided into two categories: optimality criteria method and mathematical programming method [11].…”

This paper proposes a new optimization method to solve periodic layout optimization of a cyclic symmetric structure by means of the guide-weight method. The mathematical model for periodic layout optimization under multiple constraints is built on a single working condition. By constructing a virtual fan-shaped subdomain, periodic layout optimization of the cyclic symmetric structure is transformed into the conventional topology optimization of the virtual fan-shape subdomain. Starting from the Lagrange equation, the general iterative criterion of the virtual fan-shaped subdomain is deduced by the guide-weight method. Taking the problem of minimum compliance as an example, the iterative criterion between relative density and strain energy density of elements in the virtual fan-shaped subdomain is obtained under the condition of mass constraint. The physical significance of iterative criterion is explained and the optimization flow of periodic layout optimization is provided. Two examples of the cyclic symmetric structure show that the proposed method is effective and robust to solve the problem of periodic layout optimization.
