Antennas TRIZ Cases

Modulating metamaterial element impedance shapes the far-field radiation pattern.

A calibration method for sectorized active antennas measures channel responses on sum and sector channels to form computational beamforming signals.

A hybrid beamforming method performs phase shifting in baseband and radio frequency domains to reduce power consumption.

A configurable integrated circuit synthesizes arbitrary polarizations using active beam combining and amplification.

Fused dielectric slot polarizers reduce Ohmic loss and enhance linear-to-circular polarization conversion efficiency at millimeter-wave frequencies.

Phase weights adjust adjacent antenna elements to shape radiation patterns, eliminating heat generation from amplitude attenuation.

Segmented antenna cells suppress grating lobes while enabling thinner designs and convection cooling.

Endwise electromagnetic coupling between transverse crankwire segments maintains high selectivity across oblique incidence angles while reducing physical size.

Tripole segments on a dielectric substrate filter GSM and Wi-Fi bands without stacking surfaces.

Sub-wavelength microstructures in a diffractive dielectric lens shape microwave wavefronts to reduce reflection losses and shadowing effects.

Embedded calibration elements track physical displacement via phase measurement, enabling real-time flexure estimation and maximizing array gain.

A beam cutter divides nearfield radiation to enable stationary feed horns to sample closely packed beams without mechanical movement.
