AI Technical Summary
Conventional phase shifters in sub-THz/THz frequencies operate in a narrowband manner, leading to frequency-dependent beam deviations and limited adjustment ranges, while dielectric probe antennas have lower field focusing and transitions between transmission and radiating structures reduce bandwidth and efficiency, necessitating compact, low-loss, and easily manufactured antenna elements for broadband systems.
A dielectric antenna element with a converter section featuring a tapered first antenna beam and a spaced second antenna beam forming a gap with lower permittivity gap medium, allowing for smooth signal transition and true-time delay without abrupt losses, facilitated by additive manufacturing processes.
Enables low-loss, broadband operation with adjustable propagation delay, minimizing reflections and maintaining consistent signal propagation across a wide frequency range, suitable for beam steering and array integration.
