In this article, the particle swarm optimization algorithm is used to calculate the complex excitations, amplitudes and phases, of the adaptive circular array elements. To illustrate the performance of this method for steering a signal in the desired direction and imposing nulls in the direction of interfering signals by controlling the complex excitation(More)
In this article, an optimized E-shaped patch antenna for Bluetooth (2.4–2.484 GHz) and UWB (3.1–10.6 GHz) applications with WLAN (5.15–5.825 GHz) band-notched characteristics is proposed. The dimensions of the E-shaped antenna structure in addition to the position of the slotted C-shape in the ground plane are optimized using recent optimization techniques(More)
The scientific community is still interested in heuristic techniques and optimization algorithms that could be applied in complex problems such as the antenna adaptive beam forming problem. This paper presents an empirical study of solving the problem of antenna adaptive beam forming using Central Force Optimization (CFO) algorithm. The algorithm(More)
Recently, Cognitive network has drawn the attention as a promising technology to enhance communication system performance by efficiently utilizing system resources.
