Antennas TRIZ Cases

Feed repositioning in dynamic antenna arrays shapes nulls to isolate adjacent satellites, enabling full spectrum utilization without interference.

Segmented switchable sub-groups reduce electronics quantity while maintaining scanning range and coverage area through dynamic element association.

Luneburg lens pods on wingtips reflect electromagnetic radiation to augment radar cross section across 360-degree aspect angles.

Retrodirective backscatter tags reflect modulated signals from FMCW radar readers to enable energy-autonomous operation.

The control system segments the antenna array into sub-networks to resolve the contradiction between complex network structures and precise beam direction control.

Discontinuous mesh RF shutters bridge microgaps with plasma to reflect high-power microwave radiation while allowing low-frequency signals to pass.

Rotatable quasi-optical elements and reflectors create a moving virtual antenna that reduces device complexity while maintaining high imaging resolution.

Segmented ferroelectric slabs create gradient fields to steer beams, lowering voltage and complexity.

Rotating feeds on a non-parabolic reflector shifts beam coverage locations, resolving satellite packaging constraints and interference issues.

A Gilbert cell mixer uses separate power sources to control current amplification and switch the phase position of an overcoupling signal.

A radar system augments received signal vectors to simulate a larger virtual antenna array for improved angular resolution.

Silver and barium strontium titanate layers form a hyperbolic metamaterial that reduces reflection and absorption losses while maintaining high transmission.
