“…ey also exhibited the examples of linear antenna array synthesis and proved the feasibility of the method [6]. Since then, the Taguchi method has also been widely used in the electromagnetics community, such as null realization in the specific directions of array synthesis [7,8], sidelobe optimization in the circular phased array [9], array synthesis of the conformal antenna [10], and performance optimization of the elements and arrays [11][12][13][14][15]. We know that the pattern synthesis of linear arrays can be achieved by using several other optimization methods like particle swarm optimization (PSO) [16], genetic algorithm (GA) [17], convex optimization (CO) [18], and so on; therefore, comparisons between the Taguchi method and some other optimization algorithms are necessary.…”

In this paper, a Taguchi method based on fitting and prediction is proposed to accelerate the optimization process in antenna array synthesis. The implementation procedure combines the normal Taguchi method and the curve fitting technique. A possible solution is determined by prediction based on fitting curves. Specifically, the fitting curves are obtained by using the dynamic points calculated and updated as the Taguchi method progress and recorded in the response table necessarily produced in the procedure. Test functions are used for conducting some confirmation experiments, and the results verify the validity of the proposed method. In order to illustrate its good practicability, two linear antenna arrays with a null controlled pattern and a flat top pattern, respectively, are successfully optimized by using both of the normal Taguchi method and the proposed one. Some comparisons and discussions of their results are given in the paper, which proves that the proposed method has a better practicability, not only because it inherits the global optimization characteristics of the normal Taguchi method but also because it accelerates the convergence process.

“…Taguchi method is a robust methodology based on orthogonal array (OA) concept, which effectively reduce the number of tests in the optimization process . Parameter design which adopts orthogonal experiment design used to study multiple factors and levels is the core technique in the Taguchi method.…”

“…The values of optimal levels will be as central values in the next iteration. To reduce optimization range, LD( n ) i +1 is used to next optimization iteration, whose calculating approach is following as :

LD {(n)}_{i + 1} = LD {(n)}_{i} \cdot rr = LD {(n)}_{1} \cdot {rr}^{i} = LD {(n)}_{1} \cdot RR (i)

where i is the i th iteration, rr is reduced factor, RR( i ) is reduced function. Generally, constant rr can be set between 0.5 and 1 depending on the optimization problem.…”

A novel effective radius formula is proposed for accurately calculating the resonant frequency of circular patch antennas with electrically thin and thick substrates. The formula is optimized and obtained using the Taguchi method. It is widely suitable to circular patch antennas with the electrical substrate thickness h/λd range from 0.001 to 0.2 and the dielectric constants range from 1.0 to 10.2. Compared with previous resonant frequency analysis formulae, the resonant frequency results calculated using the proposed effective radius formula are in a better agreement with the simulated and measured results. © 2015 Wiley Periodicals, Inc.

“…When antenna array elements are made closer one another, the effect of electromagnetic mutual coupling between them becomes a common phenomenon. The mutual coupling can dangerously deteriorate the performance of the array in the form of signalto-interference-noise ratio (SINR) reduction and the signal processing algorithm nonconvergence [22][23]. It precisely degrades some parameters such as the carrier frequency offset [24], channel [25], and angle of arrival estimations [26].…”

To meet the requirements of long range, small amount of data transmission, better data correctnessand less delay,a wide-Area Network State Monitoring System approach based on LoRa communication is discussed in our Project. The objective is to study and test the performance of Two communication techniques used in wide area monitoring system, a single input single output (SISO) system and a multiple input multiple output system (MIMO) in terms ofBit Error Rate(BER) with varying the signal to noise Ratio(SNR).In addition, we study the Wide Area Monitoring system based on LoRa communication. The IEEE 14-bus power system with Phasor Measurement Units(PMUs) placed at selected buses is considered. The simulation results demonstrate that the MIMO system outperform the SISO system in terms of Bit Error Rate. Furthermore, the value of the reporting rate has been varied for both systems in MATLAB to see the effect on the data correctness and the results show that the Bit Error Rate value decreases with the increase of reporting rate.Finally, we dealt with a modified LoRa MATLAB code emulator to investigate the data error and delay. The results show that LoRa Technology has better performance in terms of delay and error.
