선형 주기적 로드 안테나는 비로드 안테나와 동일한 복사 패턴을 가지면서도 더 짧은 공진 길이를 가질 수 있다.
Periodically loaded antennas can resonate at a length below that of an unloaded resonant antenna, while maintaining the same radiation pattern.
Substructure characteristic modes are reformulated using a scattering matrix-based approach, allowing for versatile applications in antenna design and computational electromagnetics.
The author presents a scattering matrix-based formulation for substructure characteristic modes, expanding the application scope to include arbitrary electromagnetic solvers.
