This paper suggests a new miniaturized antenna for radio‐frequency identification (RFID) applications of 2.45 GHz. Our structure consists of a circular microstrip patch antenna which incorporates two concentric annular slots is printed on a multilayer substrates. The bandwidth, one of the most important characteristics of antenna, can be significantly improved by using a multilayer dielectric configuration. we aim by this study to show that the effect of radiating structure loaded by annular rings for the patch size reduction as well as the advantage of this structure being to create a circular polarisation in the direction of maximal radiation pattern. The wave concept iterative procedure is used to analyse this new antenna. Using the proposed procedure, less computing time and memory are needed to calculate the electromagnetic parameters of our design. The validation of the results of our developed model was verified with known commercial software called “CST Microwave Studio Software” followed by an experimental test. According to the reached results, we can judge that our new design antenna is suitable for RFID applications in the 2.45 GHz band.

“…Te DGS is noted for its minimal space requirements and straightforward design, achieved by etching a slot in the ground plane of the microstrip circuit. Additionally, Suvarna et al [17] introduces a new pi-shaped DGS with three annular rings which is etched in the ground plane. Furthermore, Ghaloua et al [18] propose the utilization of a new geometric DGS on an FR-4 substrate with a relative permittivity equal to 4.4, a thickness of 1.6 mm, and a loss tangent of 0.025 to downsize the antenna arrays.…”

In this paper, a low sidelobe feeding network has been developed utilizing the louver-shaped defected ground structure (DGS). By adjusting the louver-shaped DGS, the output amplitude and phase of the corresponding ports can be altered, minimizing deviations from theoretical values. This enables antenna arrays equipped with this feeding network to more easily achieve low sidelobe performance. The impact of the louver-shaped DGS on the amplitude and phase of each port in the power divider within the feeding network is analyzed, and a 16-channel feeding network incorporating the louver-shaped DGS has been designed, fabricated, and then measured. The test results indicate that the performance of the line-feeding network is effectively improved by designing and adjusting the louver-shaped DGS. Through the debugging procedure, the amplitude deviation of the feeding network has been reduced from ±0.45 dB to ±0.2 dB, while the phase deviation of the feeding network has been reduced from ±8° to ±2.5°, and the maximum value of the first sidelobe has been reduced from −24.2 dB to −28.1 dB.

“…Though, optimal selection of design parameters of MPA such as patch size, substrate thickness, dielectric constant and feeding method, etc., can help achieve to operate over the desired frequency range [10][11][12]. There have been several investigations conducted with such motives; however, retaining stable and controllable performance with optimal trade-offs between dimension and performance has remained a challenge [9] [13]. During the past few years, artificial neural network (ANN) or data-driven machine learning (ML) based approaches have been proposed to estimate a suitable set of design parameters for MPA design.…”

A novel optimization concept for modeling irregular-shaped patch antenna with high bandwidth and efficient radiation attributes is proposed in this paper, along with the ability to accomplish the design at a reduced computational and cost burden. A revolutionary computing perception is established with Gravitational Search Algorithm (GSA) and Quantum Based Delta Particle Swarm Optimization (QPSO), now known as GSA-QPSO. The suggested model employed the GSA-QPSO algorithm strategically interfaced with a high-frequency structure simulator (HFSS) software through a Microsoft Visual Basic script to enhance irregular-shaped antenna design while maintaining wide bandwidth with suitable radiation efficiency over the target bandwidth region. The optimally designed microstrip patch antenna is fabricated on an FR-4 substrate with a surface area of 30×30×1.6 mm 3 . The evaluated outcome shows 96 % supreme radiation efficacy at 2.4 GHz whereas overall effectiveness is above 84% over the entire frequency range, with a nearly omnidirectional radiation pattern. In terms of impedance bandwidth, the suggested antenna offers 126.6 % over the operational frequency range from 2.34 GHz to 10.44 GHz. Fabrication and measurement results are also used to validate the simulated results. It exhibits the proficiency of the offered antenna design to be used for real-world wideband (WB) communication drives.
