Characteristic mode theory for closely spaced dipole arrays
… in this work through the lens of antenna characteristic modes. The modes of an array are calculated using the method of moments, and these modes are characterized by their radiative behavior. Additionally, the Q factor of these planar arrays is calculated using the Fourier transforms of …

Analysis and design of planar slot antennas for RFID applications using characteristic mode theory
… make use of planar antennas with good radiation characteristics to achieve electromagnetic coupling between the tag and the reader. Thin form factor, placement-insensitivity, small size and good radiation characteristics are essential qualities of planar RFID tag antennas operating in the UHF …

An analysis of the bandwidth oscillations caused by finite ground planes using characteristic mode theory
… element. This structure is then analyzed using characteristic mode theory to correlate the modal behavior of the ground plane with the bandwidth minima and maxima. Overall, bandwidth minima occur for ground plane sizes where only one mode has the highest modal significance across the band, and …

A characteristic mode perturbation approach for antenna loading design
… approaches based on experience, intuition, and modeling are challenged as the demand grows for antennas with increased functionality and performance. New systematic design methods are needed that can manage complicated performance tradeoffs while providing physical insight into the fundamental …

Synthesis process using characteristic modes for multiple in situ antennas for system radiation requirements
… with a focus on radiation pattern performance. Characteristic mode theory is commonly used to determine how structures will radiate. Solving for the modes on a structure gives the antenna designer an idea of which modes are easily excited on a structure. Each mode is associated with a modal far …

Geometry-Aware Methodology for Coupling Mechanism Analysis and Radiation Mechanism Analysis
… partial element equivalent circuit (rPEEC) model. The proposed method can quantify the capacitive and inductive coupling between the layout partitions and offers a clear physical understanding of the coupling study.</p> <p>The dipole moment is a popular equivalent noise source for digital …

Design and Detection Process in Chipless RFID Systems Based on a Space-Time-Frequency Technique
… the singularity expansion method (SEM) and the characteristic mode theory (CMT), a systematic design process is introduced by which the resonant and radiation characteristics of the tag are monitored in the pole diagram versus structural parameters. The antenna is another component of the …

Characteristic Modes for Impedance Matching and Broadbanding of Electrically Small Antennas
… goal is to describe a new, complete framework to model the fundamental behavior of small antennas. We base our analysis in characteristic mode theory which allows us to decompose the antenna behavior into the behavior of a few well-defined modes. Using this decomposition we can better understand, …
