The present work deals with the problem of restoration of a radial and balanced Electric Distribution System, that after an event causes the programmed disconnection, or not programmed, remains with one or several stretches of feeders without power. The load restoration methodology uses the automatic reconfiguration algorithm, establishing a new arrangement of closed and open interruptors that modifies the topology, seeking the reconfiguration for energy restoration that simultaneously optimizes two objectives: the load to be restored and the number of possible maneuvers. Both objectives are simultaneously optimized by the Genetic Algorithm, adapted for multi-objective optimization through the weighted sum of objective functions. In order to validate the proposed method, three electric distribution system were considered, two small size academics systems and one medium scale real system, belonging to the ANDE distribution system. The restoration results, obtained in a substantially reduced computational time, demonstrate the efficiency of the proposed method, which could be a useful tool in load dispatch and operation planning.

“…Metamaterial-based novel antennas [16][17][18][19] have the potential to overcome the stringent efficiency-bandwidth limits of traditionally manufactured small antennas. Metamaterials enable compact antenna components to span a more excellent frequency range and allow tiny platforms to use limited space better.…”

Antenna miniaturization is a typical trend in contemporary wireless systems, notably for current wireless technology, to meet multiband needs while preserving high transmission qualities. The terahertz (THz) regime is helpful in advanced applications and significantly impacts wireless technology. This paper proposes a double-layered hexagonal split ring resonator (HSRR) based on a microstrip patch antenna (MPA) and analyzes the simulated characteristics. The HSRR width is varied for different thickness "w" values and compares the analysis of with and without HSRR in the antenna. Due to the impact of metamaterials, the optimized antenna produces À44.02-dB return loss, 1.012 voltage standing wave ratio (VSWR), 6.47-dBi gain, and 4.78-dB directivity at 1.8-THz frequency. This proposed antenna is suitable for THz applications, which include high-speed data rate in wireless communication, bio-medical field, and THz spectrometer.

This paper presents a compact and wideband square microstrip patch antenna using low cost and easy available FR‐4 substrate of ground size 30 mm × 30 mm (0.51 × 0.51 at lowest resonant frequency 5.07 GHz). The radiating patch of antenna is designed by embedding three T‐shape notches of same dimension formed by two rectangular notches of size 6 mm × 5 mm and 3 mm × 2 mm. The radiating patch is optimized by parametric variation of notches and feed line. The wideband fractional bandwidth (S11 < −10 dB) of 47.2% (2810 MHz) is achieved from 4.55 to 7.36 GHz with good return loss of −47.27 dB at 5.07 GHz for an optimized dimension of notches and feed line. However, the measured fractional bandwidth of 43.9% (2340 MHz) is achieved from 4.16 to 6.50 GHz with return loss of −37.34 dB at 5.14 GHz. A stable simulated gain of 4.69 to 5.93 dBi and measured gain of 4.4 to 5.9 dBi is observed in complete resonating band. The antenna is excited by line feed of 50 Ω and simulated by IE3D simulation tool. The entire resonating band 4.55–7.36 GHz is suitable for different applications in C‐band (4–8 GHz).
