Correlation Reduction in Closely-Spaced MIMO Antenna with Circular Polarization Diversity
(Institute of Electrical and Electronics Engineers Inc., 2020)
Radiator correlation in multiple-input-multiple-output (MIMO) antenna has always been a serious concern for MIMO systems. In this paper, an antenna consisting of two parallel-placed coplanar waveguide (CPW)-fed radiators ...
Reduced-cost two-level surrogate antenna modeling using domain confinement and response features
(Nature Research, 2022)
Electromagnetic (EM) simulation tools have become indispensable in the design of contemporary antennas. Still, the major setback of EM-driven design is the associated computational overhead. This is because a single full-wave ...
Reduced-cost microwave modeling using constrained domains and dimensionality reduction
(Nature Research, 2023-12)
Development of modern microwave devices largely exploits full-wave electromagnetic (EM) simulations. Yet, simulation-driven design may be problematic due to the incurred CPU expenses. Addressing the high-cost issues ...
Expedited re-design of multi-band passive microwave circuits using orthogonal scaling directions and gradient-based tuning
(Nature Research, 2024-12)
Geometry scaling of microwave circuits is an essential but challenging task. In particular, the employment of a given passive structure in a different application area often requires re-adjustment of the operating ...
Highly integrable planar-structured printed circularly polarized antenna for emerging wideband internet of things applications in the millimeter-wave band
(Nature Research, 2024)
This paper proposes a numerically and experimentally validated printed wideband antenna with a planar geometry for Internet of Things (IoT) applications. This design tackles the challenges associated with deploying IoT ...
