Antenna Earthings TRIZ Cases
- Broadband UHF Antenna Assembly With FSS-HIS Miniaturization
FSS, HIS, and anisotropic magneto-dielectric layers shrink UHF antennas while preserving bandwidth, efficiency, and radiation performance.
- Compact Antenna Loop Structure for Uniform 2.4 GHz Radiation
A bent compensation loop and ground gap help a compact 2.4 GHz antenna achieve more uniform radiation for WiFi, Bluetooth, and Zigbee.
- Quarter-Wave Feeder Line Layout for Antenna Noise Suppression
A quarter-wave grounded feeder line forms a band-pass path that blocks noise propagation and protects high-frequency antenna IC operation.
- Slotted Grid Array Antenna Layout for Stable Millimeter-Wave Fan Beams
Perpendicular slots and vias let a grid array antenna hold broadside fan beams with high gain and low side lobes across millimeter-wave bands.
- Base Station Phase-Shifting Feed Structure Without Coaxial Cables
A U-shaped metal cavity and shared ground plane replace coaxial feeding, cutting antenna phase-shifter thickness, weight, and assembly complexity.
- Dual-Polarized Microstrip Patch Array With Differential Feed Isolation
Differential feeding with parasitic and radiating patches improves polarization purity and orthogonal-port isolation in scanned antenna arrays.
- Tapered Monopole Antenna for Wideband PD Localization
A tapered monopole with microstrip feed broadens UHF bandwidth in a compact antenna for partial discharge detection and localization.
- Quasi-N-Bit Metasurface Antenna Using Mixed 1-Bit Unit Cells
Mixing 2N−1 types of 1-bit unit cells enables near N-bit beam steering while reducing control-circuit complexity, loss, and heat.
