Particular Array Feeding Systems TRIZ Cases

A grooved radome nests a second antenna and side feed network to add bands while limiting antenna thickness and frontal area.

A reflector redirects antenna-array beams so a lens can sit closer without losing gain, helping shrink mmWave antenna modules.

Splitting baseband signals into direct and combined antenna feeds enables multi-beam control with fewer ports and lower beam-forming complexity.

A triangular tripole loop with one 0/120/240° feed maintains circular polarization at large scan angles while reducing active RF channels.

By placing two conductor baluns in the same plane, this antenna case frees space for tighter multi-band array integration.

Separate feeder lines and a band-selective filter simplify multiband antenna layout while avoiding coaxial cable complexity and inter-band interference.

A closed-loop 5G antenna module uses conductive adhesive and air-gap signal lines to cut calibration complexity, tolerances, and loss.

A switchable horizontal feeding network changes port connections to vary transceiver channel count without replacing the base station antenna.

A cancellation signal offsets spatial coupling from the primary antenna, protecting diversity reception sensitivity and the low-noise amplifier.

Alternating voltage polarity and level across liquid crystal elements suppresses burn-in and keeps beam or reflection direction stable over time.

Differential PA outputs drive paired antenna monopoles through a balun, avoiding splitter loss while improving radiation symmetry and signal strength.

An integrated feeding base plate and radiation structure removes welding points, cutting antenna assembly complexity while preserving MIMO performance.

Staggered radiating rows increase element spacing to cut coupling, improve radiation efficiency, and strengthen dual-beam isolation.

Selective antenna port switching adapts MIMO paths to signal strength, improving reception while avoiding power waste on weak paths.

A dielectric layer and metallic support improve mmWave antenna frequency characteristics and isolation while keeping the module compact.

Ground-pad and signal-line layout cuts radiation from vertical PCB connections, reducing millimeter-wave insertion loss between antenna and transceiver.

A low-pass filter lets low- and high-frequency antennas share one feed point, saving clearance area while preserving band isolation.

Orthogonal antenna arms and stacked feed layers expand 5G millimeter-wave bandwidth, improve port isolation, and widen beam scanning range.

A buffer element absorbs liquid crystal expansion, keeping substrate spacing stable and antenna performance consistent across temperatures.

An integrated waveguide launcher and land grid array remove air gaps in mm-wave package-to-PCB transitions, cutting signal loss and mismatch.

A compact tower enclosure combines power and fiber distribution with overvoltage protection to cut cabling, save space, and reduce energy loss.

A choke cavity around the balun and phase shifter suppresses cross-band radiation, improving multi-band antenna coverage and space use.

A same-layer feed and ground antenna layout boosts 5G millimeter-wave bandwidth and radiation efficiency in space-limited display devices.

Sequential rotation feeding and orthogonal patch placement widen circular polarization bandwidth while keeping low axial ratio and high gain.

Aligned phase centers in staggered radiating arrays reduce mutual coupling and radiation pattern distortion during elevation beam steering.
