Antennas TRIZ Cases

Movable LNBFs around a spherical lens create independent narrow beams for compact, simultaneous tracking of multiple satellites across a hemisphere.

Dual-thickness dielectric regions steer 24 GHz+ reflections without photomasks, cutting production time and cost while preserving phase accuracy.

A silicon gradient-index lens uses concentric equal-depth holes to focus terahertz radiation while reducing thickness, losses, and antenna alignment issues.

Separated reflector units shift in-plane to steer radio waves mechanically, cutting power use and cost while expanding high-frequency coverage.

A non-uniform etched coating in transmissive glass reduces RF attenuation and steers phase to improve indoor signal coverage.

A multi-sided Luneburg lens with a PUMA array and anti-reflective layer enables wideband hemispherical beam steering without complex phase shifters.

Discrete switchable impedance elements replace varactor tuning to stabilize metamaterial control, lower voltage demand, and speed switching.

Memristor-switched RIS cells hold antenna states without continuous power, cutting static energy use while enabling fast beamforming control.

Axially layered magnetic metamaterials inside a surrounding coil boost permeability, bandwidth, and efficiency in compact HF antennas.

Programmable unit-cell phase control lets a metasurface steer EM reflections over wide incidence-to-reflection angles with rapid reconfiguration.

Passive Risley prisms steer three monopulse patterns without active RF networks or gimbals, cutting antenna complexity and cost.

Multiple coupled resonators and a reference conductor stabilize wideband radio wave reflection, phase linearity, and frequency response.

Matrix RIS unit cells use liquid crystal phase control and trench electrodes to redirect blocked signals with lower power than repeaters.
