“…This pattern was originally synthesized by the touring ant colony optimization (TACO) algorithm with 20 equal spacing elements. For this problem, the FBMPM-based synthesis method has been proposed in [16], where only 15 elements were used to obtain the same cosecant main beam and the same PSLL of [15]. Now, using the proposed IWO-CVX method, an improved PSLL of −26 dB with the same cosecant main beam has been achieved compared to the FBMPM method in [16].…”

Abstract-A hybrid algorithm based on the invasive weed optimization (IWO) and the convex optimization (CVX) is proposed for minimizing the peak sidelobe level (PSLL) of linear array with focused and/or shaped beam pattern. In this approach, IWO is adopted to produce the array (described by element positions), and CVX is used to determine the excitations for each produced array. Then the corresponding PSLL acts as the fitness function of IWO to find the optimal positions which lead to the minimum PSLL. Numerical experiments are conducted to validate the effectiveness and robustness of the proposed hybrid approach. Compared with other techniques, a lower PSLL can be achieved with a fixed main beam width or with a shaped main beam using this hybrid algorithm. Moreover, this method can easily cope with some constraints on the aperture, such as the minimum element spacing and the total number of elements.

“…In general, the design and implementation of the circuitry feeding the array are simpler if the element excitations corresponding to different patterns differ only in phase than if they also differ in amplitude. Several methods of generating multiple pattern antenna arrays either by phase or by other methods have been described [1][2][3][4][5][6][7][8][9].…”

In this paper, we present a new method based on real-coded Genetic Algorithm (GA) with elitist model for optimal design of a reconfigurable symmetrical dual-beam uniformly spaced linear isotropic antenna array with phase-only control of quantized phase shifters. The problem is to find a common amplitude distribution that will generate a pencil beam with zero phases and a flat-top beam with discrete phases of a six-bit discrete phase shifter, without or with pre-fixing the value of dynamic range ratio (|I max /I min |) of excitation current amplitude distribution equal to or less than five.

“…Synthesis of unequally spaced array antenna by adjusting the amplitude or position of the elements has become an interesting category during recent years, because it reduces the size, weight and number of elements in array antennas [1][2][3][4][5][6][7].…”

Abstract-An efficient hybrid method is presented to obtain the current distribution of both non-uniformly linear and planar arrays by sampling the array factor of a desired radiation pattern. The proposed method provides Fourier coefficients and uses the Least Mean Square method (LMS) to solve the system of equations in order to obtain current distribution in associate with the desired radiation pattern. The obtained level of first Peak Side Lobe Level (PSLL) is 3 dB lower than the level of first PSLL using conventional methods such as LMS method or Legendre function method.
