The proposed antenna structure is made up of four (4) monopole elements, each consisting of a stripline-fed stub with a via sandwiched between two dielectric substrates. Each dipole resonates at 70 MHz when isolated. This paper describes the synthesis method of linear array geometry for side lobe level and null control using the Genetic Algorithm, an iterative stochastic optimizer that works on the concept of survival of the population values based on the fitness value. Often, the array elements are identical. One C-shaped slot and two PIN diodes are integrated into the circular patch to achieve polarization reconfiguration. The radiating elements used to construct the array are double-sided printed dipoles For the linear large-scale antenna arrays (LSAA) of transceivers placed in random locations in 3D space, a simple but accurate closed-form expression is derived to characterize the spatial bandwidth. The default linear array is a two-element dipole array. This is not necessary, but it is practical and simpler to design. 6 days ago · A 1×2 antenna array with three-parameter independently controllable reconfiguration of polarization, frequency and radiation pattern is proposed. The antenna has been designed to operate in the GHz frequency range, covering both the receiving and transmitting SOTM Ku bands, namely, GHz and GHz, respectively. The linearArray object creates a linear antenna array in the xy -plane. Multi-polarized arrays can also reject interfering signals having different polarization states from the desired signal, even if the signals have the same direction of arrival. 149 [2] The individual antennas (called elements) are usually connected to a single receiver or transmitter by feedlines that feed the power to the elements in a specific phase relationship. Sep 19, 2025 · A. Compared to conventional probe-fed coupled arrays, the proposed antenna design realized a This research has proposed the improved iterative generic algorithm (GA) optimization scheme by using multi-parents crossover and adaptation mutation to synthesize the radiation pattern of an aperiodic (nonuniform) linear array antenna.

Root-MUSIC algorithm is found to reduce the computational complexity and increase the speed with good accuracy. To achieve the 5 days ago · Introduction Near-field (NF) source localization is attracting increasing attention, especially in mobile communications, due to the development of Extremely Large Antenna Arrays (ELAAs) envisioned for 6G. It highlights … An antenna array (or array antenna) is a set of multiple connected antennas which work together as a single antenna, to transmit or receive radio waves. . 6 This paper presents a study on direction finding using Time Modulated Antenna array with Root-MUSIC algorithm for multiple non-coherent sources in the presence of white gaussian noise. 29% from 27. ) The As phased arrays begin to include more mixed-signal and digital content, there are many engineers who could benefit from a much more intuitive explanation of phased array antenna patterns. Explore linear, planar and conformal antenna arrays with examples. The 5 days ago · In this paper, we present the design of a high-performance dual-linearly polarised broadband stacked patch antenna array for SATCOM on-the-move applications. , vol. 11ac outdoor applications. Four sector-shaped parasitic patches and four varactor diodes are employed to obtain frequency reconfiguration. The mutual coupling is reduced by utilizing a decoupling structure integrated within the array to generate a 180-degree phase reversal with the interfering signal. The individual elements may be of any type (wire dipoles, loops, apertures, printed antennas, etc. Gupta, “Multiobjective genetic optimization of nonuniform linear array with low sidelobes and beamwidth,” IEEE Antennas Wireless Propag. The dipoles are center-fed. Another way to increase the electrical size of an antenna is to construct it as an assembly of radiating elements in a proper electrical and geometrical configuration – antenna array. 1547–1549, 2013.
