“…In present-day Base Transceiver Station (BTS) systems, as well as in mobile devices, there is a tendency to employ Multiple-Input Multiple-Output (MIMO) antennas to achieve channel diversity [1][2][3][4][5][6]. Usually, elementary antennas in such MIMO systems (or antenna arrays) can be realized with inexpensive Printed Circuit Board (PCB)-based techniques (e.g., microstrip or coplanar) and can be used for transmitting and receiving all kinds of information [7][8][9][10][11][12][13][14].…”

Conventional beamforming methods for reconfigurable reflector antennas assume full control over the amplitude and phase of the reflected field. Here, we develop a novel beamforming methodology for reflecting Programmable Metasurfaces (PMS) with capacitive memory. Although utilizing such fully reactive PMS simplifies antenna design and reduces energy consumption, the PMS reflection magnitude is unity and thus a global optimization of the reflection phases over the PMS unit cells is required in each beamforming scenario. We propose an implementation of such an optimization method rooted in the traditional Fourier transform-based beamforming and evaluate its performance. Additionally, we show that a pair of trained feed-forward neural networks (FFNN) with one input, one hidden, and one output layer can replace time-consuming global optimizations in the case of a PMS comprising 3×10 unit cells. We train the FFNNs on a dataset obtained for typical single- and dual-beam beamforming scenarios. After training, the FFNNs perform requested beamforming tasks within a fraction of second and with about the same accuracy as the original optimization algorithm. The proposed methodology may find applications in future mobile telecommunication systems that require real-time beamforming on low-end hardware. The same beamforming methodology can be also employed in short-range wireless power transfer systems.

“…The MIMO antenna is designed by designing radiation elements individually, then by putting these elements together in the next step [7]. Today, printed antennas have become more popular due to their light structure, cheapness, and ease of connection to other microwave components [8,9,10]. One of the most critical challenges in designing an antenna is choosing its optimal physical parameters to achieve proper antenna performance.…”

This study introduces a novel multi-objective optimization algorithm integrating Customized Mutated PSO (CM-PSO) and an innovative modified Genetic Algorithm (GA) using an unexplored merged chaotic map. The hybrid algorithm con- verges to desired results faster than CM-PSO and modified GA without trapping in local minima. Validation is conducted by designing a single-element and simple-structure dipole antenna so that its optimized S 11 is better than -30 dB at the resonance frequency and covers the 3.3 to 3.8 GHz fre- quency band with S 11 < − 1 0 dB. Certainly, the -30 dB and covering frequency band criteria can be modified in the pro- posed algorithm. In the algorithm, the isolation between el- ements of a quad-Multiple-Input/Multiple-Output antenna, constructed using optimized dipole antennas, is set to be less than -20 dB (changeable criteria) so that the smallest size can be achieved. CST carries out electromagnetic and high- frequency simulations, and the novel developed optimization algorithm in MATLAB determines what and how much pa- rameter values need to be changed by CM-PSO or an innova- tive modified GA in order to enhance the antenna’s S 11 result and its Impedance Bandwidth (IBW). The input parameters of the algorithm are the dimensions of the proposed antenna’s elements, which significantly influence its performance.

A compact printed dipole antenna using an integrated balun is introduced in this work, which is achieved three frequency bands by using C-shaped resonators. The total dimension of the proposed antenna is 42 × 72 mm 2 , and it covers the frequency bands of 1. 62-1.88, 2.36-2.81, and 5.15-6.16 GHz with S 11 < −10 dB. Furthermore, the measured peak gains of the antenna in three frequency bands are equal to 8.52, 9.46, and 6.81 dB, respectively. Dipole antennas with integrated baluns have a main frequency band based on the length of the dipole arms. Nevertheless, in the presented design, two additional frequency bands have been created for the antenna, by producing suitable magnetic couplings between the C-shaped resonators and the Γ-shaped feed line innovatively, which has a better radiation behavior, unlike traditional triple-band antennas. An equivalent circuit of the introduced antenna has been investigated and afterward, the optimized antenna has been fabricated and tested.
