“…Roy et al [18] used a modified IWO algorithm to design non-uniform circular antenna arrays. IWO methods have also been successfully applied to radar to perform circular antenna array synthesis [19], time-modulated linear array synthesis [20], sidelobe reduction [21], large array synthesis [22] and optimizing antenna configurations [23].…”

An approach for using a Genetic Algorithm (GA) to select radar design parameters related to beamforming and angle of arrival estimation is presented in this article. This was accomplished by first developing a simulator that could evaluate the localization performance with a given set of design parameters. The simulator output was utilized as part of the GA objective function that searched the solution space for an optimal set of design parameters. Using this approach, the authors were able to more than halve the mean squared error in degrees of the localization algorithm versus a radar design using human-selected design parameters. The results of this study indicate that this kind of approach can be used to aid in the development of an actual radar design.

Abstract-A novel compact four element multiple input multiple output (MIMO) antenna is proposed. The antenna is composed of four E-shaped patch elements and operates at 5.8 GHz. The single Eshaped patch antenna, operate at this frequency is designed using the Invasive Weed optimization algorithm. This algorithm is then applied to design the selected orthogonal polarization arrangement for two and four element MIMO antenna for high degree of isolation. In order to measure the array performance under MIMO signaling conditions a multi-port metric is used to characterize the compact array rather than the scattering matrix characterization. The designed antennas have low profile, easy fabrication, low cost and good isolation. The simulation and measurement results of reflection coefficient, mutual coupling and radiation pattern are presented.

“…Following this tradition, in 2006, Mehrabian and Lucas proposed the Invasive Weed Optimization (IWO) [13], a derivative-free, metaheuristic algorithm, mimicking the ecological behavior of colonizing weeds. Since its inception, IWO has found successful applications in many practical optimization problems like optimization and tuning of a robust controller [13 ], optimal positioning of piezoelectric actuators [14], developing a recommender system [15], antenna configuration optimization [16], design of E-shaped MIMO Antenna [17], design of encoding sequences for DNA computing [18], and design of compact U-array MIMO antenna design [19].…”
