Polarised Antenna Unit Combinations TRIZ Cases
- RF Lens Antenna Array for Rectangular Beam Coverage
Unequal amplitude and phase across a planar RF array and lens creates rectangular venue coverage with fewer holes and steadier power.
- Dual-Board Patch Array Antenna for Wideband Polarization Isolation
A stacked radio board and dual antenna boards improve gain bandwidth, conversion efficiency, and horizontal-vertical isolation in patch arrays.
- Patch Antenna Cavity Structure for Wide-Angle Radiation
A cavity above a single patch antenna broadens radiation directivity without antenna arrays, cutting size, circuit complexity, and cost.
- Waveguide Slot Antenna Surface Structure for Multiple Reflection Suppression
Periodic ridges and grooves on a waveguide slot antenna redirect incident waves to suppress multiple reflections without added surface units.
- Polarized Radar Antenna Layout for Low-Coupling 3D Positioning
A mixed parallel- and cross-polarized receive array cuts transmit coupling while preserving target signal strength for accurate 2D and 3D positioning.
- Metasurface Steerable Antenna for Wide-Angle Beam Steering
Solid-state switched metasurface cells steer beams in any direction, avoiding phased-array RF complexity and low-elevation scan loss.
