Microstrip antenna has been designed and applied to many practical scenarios for wireless communications. To meet the increasing requirements of wireless communication and quality of service, array antenna design deserves studying and analyzing. A novel design of 2.45-GHz microstrip array antenna has been proposed in the paper. The novel array antenna is composed by a planar layout of elements, coaxial feeders and circular feed points. The array antenna is designed to satisfy practical requirements, including frequency channel, voltage standing wave ratio, impedance matching, and signal loss rate. A memetic of genetic algorithm and the quasi-Newton method is proposed to effectively solve the design model. Numerical simulations are performed by the five optimization methods and two array sizes. The results show that the proposed design is able to produce qualified microstrip array antenna for usage. The proposed memetic method is more effective than the other four methods. The microstrip array antenna will be useful for practical wireless communication systems. INDEX TERMS Array antenna, genetic algorithm, microstrip antenna, quasi-Newton method, wireless sensor.

“…A large number of variations in the feature vector's dimensions have been made, which indicates that the highest and maximum accuracy was achieved by decreasing the feature vector for both subjective objects [17]. The proposed method uses the KPCA method, which, given that this method has much more precision in cases where it has many features, shows that the obtained results have a higher accuracy than the PCA method, which is shown in the following table in comparison with the method View Available Table 2 [2,[4][5][6][7]. …”

“…However, Elliot was the one who presented the design equations for slot arrays on a rectangular waveguide [16]. In the study by Oraizi et al [17], a design algorithm for an edge slot array is proposed with non-uniform spacing on a rectangular waveguide. Slotted arrays on a cylindrical waveguide were initially studied by Wait et al [18].…”

In the current work, for the first time, the design equations for an array of rectangular slots axially placed on a cylindrical waveguide are driven and presented, making it possible to attain asymmetrical and non-broadside patterns with higher bandwidths. The method of least squares is then used for both the radiation pattern synthesis with the specified side lobe level, and the array input impedance matching. For optimization, the error function comprised of the three terms of impedance matching, array pattern synthesis, and slot design equations is constructed. To minimize the error function, the genetic algorithm combined with the conjugate gradient method is utilized, as well as the geometrical characteristic of the slots which are defined. This procedure increases the design speed and provides the means to synthesize any desired pattern for an array of axial rectangular slots on a cylindrical waveguide. Numerical and fabrication examples are presented as illustrations of the proposed synthesis method The results of the proposed method are verified by using the commercial software High-Frequency Structure Simulator (HFSS) in comparison to measurement results obtained out of the proposed prototype of a fabricated antenna operating at the frequency of 9 GHz. INDEX TERMS slotted cylindrical antenna, axial slot array, design equations, Method of Least Squares (MLS), genetic algorithms.
