“…The available mathematical modeling of patch antennas is based on rectangular patch. Although due to the four cutting slots in radiating patch the overall size calculation is not straightforward as simple rectangular patch antenna, it has been optimized using HFSS optimetrics [16,[25][26][27]. The electromagnetic wave propagates toward the endfire direction headed by the parasitic director element on the top while acting as an impedance matching element simultaneously.…”

A low profile, compact dual band slotted patch antenna has been designed using finite element method-based high frequency full-wave electromagnetic simulator. The proposed antenna fabricated using LPKF printed circuit board (PCB) fabrication machine on fiberglass reinforced epoxy polymer resin material substrate and the performance of the prototype has been measured in a standard far-field anechoic measurement chamber. The measured impedance bandwidths of (reflection coefficient<-10 dB) 12.26% (14.3–16.2 GHZ), 8.24% (17.4–18.9 GHz), and 3.08% (19.2–19.8) have been achieved through the proposed antenna prototype. 5.9 dBi, 3.37 dBi, and 3.32 dBi peak gains have been measured and simulated radiation efficiencies of 80.3%, 81.9%, and 82.5% have been achieved at three resonant frequencies of 15.15 GHz, 18.2 GHz, and 19.5 GHz, respectively. Minimum gain variation, symmetric, and almost steady measured radiation pattern shows that the proposed antenna is suitable for Ku and K band satellite applications.

“…For comparison, several different PML algorithms are carried out in this section. They include the conventional CFS-PML in BOR-FDTD algorithm (FDTD-PML) in [39], the CFS-PML in original ADI algorithm (ADI-PML) in [26], the CFS-PML in CNAD algorithm in [27], the uniaxial PML (UPML-HFSS) of HFSS in [40], the convolutional PML (CST-CPML) of CST in [41], and the Mur absorbing boundary condition (Mur) in [29]. For clarify illustration, the proposed scheme is denoted as CE-CNDG-PML.…”

Unconditionally stable approximate Crank-Nicolson (CN) perfectly matched layer (PML) implementation is proposed to treat open region problems for a bandpass rotational symmetric structure. To be more specific, this implementation is based upon the CN Douglas-Gunn (DG) procedure and the complex envelope (CE) method in body of revolution (BOR) finite-difference time-domain (FDTD) lattice. The proposed scheme inherits the advantages of the CNDG procedure, CE method, and BOR-FDTD algorithm which can improve the efficiency, enhance the absorption, and maintain the calculation accuracy. The effectiveness which includes accuracy, efficiency, occupied resources, and absorption is illustrated through a numerical example. The numerical results reveal that the proposed scheme provides considerable accuracy, creditable absorption, and outstanding efficiency. Meanwhile, it can also verify that the proposed scheme is stable without the limitation of Courant-Friedrich-Levy (CFL) condition.

“…The other PMLs occupied 10 grids. The proposed scheme was also compared with the PML schemes which are used in commercial software, including the uniaxial PML (FDTD-UPML) in Ansys and convolutional PML (FDTD-CPML) in CST Studio [20,21]. Different problems were considered, including the wave radiation problem of a metamaterial structure and the wave transmission problem of an integrated circuit.…”

Based on the alternating direction implicit (ADI) procedure, leapfrog formulation, and a higher order PML scheme, we propose an unconditionally stable perfectly matched layer (PML) algorithm with improved absorption to treat open regions in a finite computational domain with improved overall performance. The proposed algorithm performed well compared to other algorithms during simulations. We further demonstrated the proposed scheme’s effectiveness using numerical examples. We found that the proposed scheme had enhanced effectiveness and improved the absorption during the whole simulation. Furthermore, it was able to break the stability condition, proving that it is an unconditionally stable scheme.
