Antenna Couplings TRIZ Cases
- Pluggable Receiver Splitter for 2T2R Microwave Radios
A ridged-waveguide circulator plate with a pluggable insertion plate provides variable coupling factors without altering the PCB board.
- Miniaturized Planar Inverted Folded Antenna for Mountable UHF Tags
A folded planar antenna device with a binocular-shaped slot balances microstrip impedance.
- Edge-Enabled Void Isolator for Antenna Isolation
An edge-enabled void isolator provides electromagnetic isolation between antennas using tunable capacitance and inductance structures.
- Tunable Antenna Isolator Using EBG and Metallic Walls
A tunable antenna isolator combines metallic walls with electromagnetic band-gap structures to resist surface and free-space interference.
- Radar Leakage Suppression via Adaptive Delay Compensation
A radar front-end uses a compensation unit to generate a reference signal that corrects leakage path delays before mixing with echoes.
- Dual-band Patch Antenna Using Vertical Stacking
Vertical stacking of patch antennas on a dielectric support resolves interference between frequency bands while reducing assembly weight.
- Resonator Decoupling Network for Compact Antenna Isolation
A resonator network connects transceivers to antennas, configuring coupling coefficients and resonance frequencies to achieve desired port matching.
- In-situ Mutual Coupling Characterization for Scanned Array Antennas
Sequential switching with a 2-port analyzer measures mutual coupling in scanned arrays, reducing the cost of multi-channel equipment.
