Circular antenna synthesis using multiverse optimizer

Kerim GÜNEY | Erhan KURT

Antenna array synthesis is one of the most popular topics in the electromagnetic field. Since achieving a desired antenna radiation pattern is a mathematical problem, in the literature, there are various optimization algorithms applied to the synthesis process of different kinds of antenna arrays. In this study, Multiverse Optimizer (MVO) and modified MVO (MMVO) are used to perform circular antenna array (CAA) synthesis. During the exploration, exploitation, and local search phases of calculation, MVO uses three concepts in cosmology; white hole, black hole, and wormhole. Convergence capabilit ...Daha fazlası

Effective side length formula for resonant frequency of equilateral triangular microstrip antenna

Kerim GÜNEY | Erhan KURT

A novel and accurate expression is obtained by employing the differential evolution algorithm for the effective side length (ESL) of the equilateral triangular microstrip antenna (ETMA). This useful formula allows the antenna engineers to accurately calculate the ESL of the ETMA. The computed resonant frequencies (RFs) show very good agreement with the experimental RFs when this accurate ESL formula is utilised for the computation of the RFs for the first five modes.

Synthesis of thinned planar s using 0-1 ınteger linear programming method

Erhan KURT

This paper proposes a fast optimization method for synthesizing thinned planar antenna arrays. A 0-1 integer linear programming (ILP) model was proposed for the antenna array optimization. This model mainly aims to minimize the peak sidelobe level (PSLL) and consider the design requirements of narrow beamwidth and high directivity, finally obtaining the optimal distribution of the turned “ON” element positions in the aperture. Several cases of planar array designs with different aperture sizes and scan angles were provided in the paper and compared with other popular algorithms. Numerical resu ...Daha fazlası

Sidelobe level suppression for elliptical antenna arrays using modified Salp swarm algorithm

Erhan KURT | Kerim GÜNEY

In this study, a modified version of salp swarm algorithm (MSSA) is used to synthesize elliptical antenna arrays (EAAs).The original salp swarm algorithm (SSA) is an optimization algorithm inspired by the behavior of salps in nature, which isused to solve engineering problems. The main purpose of the synthesis in this study is to obtain an EAA pattern with lowmaximum sidelobe levels (MSLs) for a fixed narrow first null beamwidth (FNBW). For different examples, the amplitude andangular position values of the antenna array elements are considered as optimization parameters. To show the effective ...Daha fazlası

Synthesizing of concentric circular antenna arrays by using a combination of ant lion optimizer and sequential quadratic programming

Kerim GÜNEY | Erhan KURT

Antenna array synthesis is quite a popular topic in electromagnetics and finding suitable array parameter values is a challenging nonlinear engineering problem in this field. In recent years, it has been realized that optimization algorithms can be used to achieve desired solutions in this area. Besides, improvements in the optimization algorithms make it possible to perform synthesis processes on different array structures and to obtain better results. In this paper, a method based on a combination of ant lion optimizer (ALO) and sequential quadratic programming (SQP) is proposed for the conc ...Daha fazlası
