Antenna Earthings TRIZ Cases
- Reconfigurable Dual-Polarized Antenna for Beam Switching in Dense WLANs
Diode-controlled beam switching lets a dual-polarized antenna alternate between omnidirectional coverage and high-gain directional links in dense WLANs.
- Steerable L-Band Patch Antenna for Low-Elevation Gain
Difference beam steering and a crossed metallic fence help an L-band patch antenna keep high gain near the horizon while widening coverage.
- Compact Slot Antenna Layout for RF Desensitization Reduction
Orthogonal slot sections and a metal trace cut internal noise coupling, improving signal reception in compact wireless devices.
- Monopolar Wire-Plate Antenna With Parallel Shorting Wires
Parallel magneto-dielectric coated shorting wires lower monopolar wire-plate antenna resonance for compact size without added bulk or loss.
- Wireless Terminal Stub Structure for Lower SAR and Radiation Loss
Symmetrical metal stubs counter body-induced currents in a wireless terminal, reducing SAR and preserving antenna radiation efficiency.
- Peripheral Electrode Antenna Layout for Orthogonal Radiation
A peripheral electrode linked to a ground pad lets a flat antenna radiate sideways to the substrate while preserving gain and impedance matching.
- Z-Slot Waveguide Antenna for Cross-Polarization Isolation
Z-shaped slot coupling between input and output waveguides boosts cross-polarization isolation to 65 dB while keeping a compact 73-78 GHz antenna.
