Parallel-Plate/Lens Fed Arrays TRIZ Cases

Dual converging and diverging metasurface lenses widen phased array scan range while limiting reflection loss and directivity degradation.

Pre-tensioned substrate membranes keep RF polarizers flat under vibration and temperature change while avoiding foam spacer dielectric losses.

Dual phase-shifting surfaces enable compact 2D beam scanning with fewer control lines, avoiding bulky mechanical antenna steering.

Dual reconfigurable phase-shifting surfaces steer a low-profile antenna beam in two axes while reducing bulk, power use, and control complexity.

Varying slot angles by azimuth and tuning guided wavelengths helps a waveguide antenna keep bandwidth and polarization in tilted directions.

Dielectric lenses and integrated RF scanning arrays raise radar gain and angular resolution while limiting distribution losses and sensor size.

A phased array feeds a gradient-index lens to overcome discrete focal-point scanning, enabling wide beam steering with a smaller, lower-loss antenna.

Tilted feeds and vertically offset spherical lenses reduce signal intersections and grating lobes while supporting more RF beams.

Superposed beam and network port stages with a resistive film cut coupling and overlap losses while maintaining antenna gain and reducing bulk.

Individually steerable antenna modules with rotational symmetry form multiple SATCOM beams while cutting power use and hardware cost.

Variable capacitance tuning controls slot resonance and mutual coupling to steer beams in radial line slot antenna arrays with low size and power.

A hybrid coaxial launcher feeds stacked parallel plate waveguides to create two independent beams without enlarging antenna footprint.

Pre-tensioned substrate membranes replace foam spacers and adhesives to keep RF polarizers flat and cut dielectric loss under thermal stress.

A mask-pattern Fresnel lens focuses 5G waves from different incident angles onto one antenna region, boosting gain and easing array alignment.

A surface waveguide feed and via-connected varactor bias layout enables beam scanning while reducing RF interference, dielectric loss, and bandwidth limits.

Uniform diode orientation with rotated antenna irises compensates resonance shifts, improving beam steering and manufacturability.

A curved antenna layout keeps off-axis elements closer to the lens, reducing aperture mismatch, cross-talk, and MIMO signal separation complexity.

A pillbox beamformer and non-resonant subwavelength metasurface deliver beam focusing in a lighter, flatter antenna for harsh environments.

Separating gridded and non-gridded radiation layers improves waveguide array manufacturing accuracy, cross polarization, and side lobe control.

A dielectric plate with metallic patches enables capacitive coupling between parallel waveguides in steerable antennas.
