Particular Array Feeding Systems TRIZ Cases
- Multi-Stage Antenna Decoupling Circuit for Broadband Isolation
Cascaded decoupling stages cancel self-interference between antennas, improving full duplex radio isolation across wide frequency bands.
- Multi-IC Radar Array Layout for Larger Aperture Resolution
Multiple radar ICs connected to antenna elements in series expand array aperture length and improve spatial resolution for direction estimation.
- Multilayer Signal Coupler Layout for High-Coupling MBFNs
Middle-layer windows and trace geometry raise coupler coupling above 3 dB while protecting return loss and isolation in MBFNs.
- Nested Antenna Cluster Layout for Compact Multi-Antenna Devices
Partially sleeved adjacent antennas share space to support multiple functions while reducing device volume and improving radiation efficiency.
- Series-Fed Patch Antenna Layout for Horizontal Polarization
Differential feed lines between successive patch elements enable horizontal polarization while preserving array behavior for orthogonal radar modes.
- Metasurface Antenna Layout With Single-Feed High-Gain Coupling
A single strip feedline and coupling aperture simplify metasurface antenna feeding while preserving compact size, broadband response, and high gain.
- Quad-Feed SIW Antenna for Dual Circular Polarization Coupling
Quad-feed SIW coupling uses dual circular polarizations and impedance matching to support low-loss bidirectional millimeter-wave links.
- Stacked UWB Antenna Array Layout for Smaller Device Footprint
Overlapping stacked radiation patches and short-circuit walls shrink UWB antenna area while preserving radiation efficiency across target bands.
- Amplifier Efficiency Control in Coupled Antenna Arrays
Dynamic bias and impedance compensation helps antenna-array amplifiers maintain output efficiency despite coupling, load shifts, and scan-angle changes.
- Conformal Array Antenna Pattern Synthesis with Reduced Optimization Load
By optimizing sub-array aperture distributions instead of each element, this case speeds conformal antenna pattern synthesis while meeting beam requirements.
- Series-Fed Planar Antenna Layout for Horizontal Polarization
Differential feed lines and an off-axis excitation point let a series-fed planar antenna achieve horizontal polarization for polarimetric radar.
- Reciprocal Ferrite Switch Layout With Low Insertion Loss
A coupler, two ferrite circulators, and a magic T create reciprocal switching while avoiding the complex structure and high insertion loss of conventional designs.
- Waveguide Antenna Layout for Multi-Directional ADAS Sensing
Separating and receiving pipes let one waveguide antenna send and collect signals in multiple directions, removing ADAS blind zones.
- Antenna Module Layout With Peripheral Electrode for Limited Ground Area
A peripheral electrode boosts capacitance and controls electric fields so compact antenna modules keep resonant frequency and bandwidth with less ground area.
