Modular Arrays TRIZ Cases

Vertical transmit and receive cards move RF functions out of the aperture, cutting layer complexity, easing thermal management, and enabling tile reconfiguration.

Spacing elements set a precise air gap between stacked boards, simplifying phased-array antenna fabrication while maintaining WiGig bandwidth coverage.

Removing the radome lets the antenna RF module shed heat front and rear, while a reflector grounds the radiator and conducts RF filter heat outward.

Alternating circularly polarized transmit and receive antennas with phase shifting cuts array area while maintaining isolation and beam forming.

Alternating antenna elements on opposite substrate surfaces suppress grating lobes while preserving gain and practical feeder layout.

Dielectric RF lenses increase phase difference between closely spaced antennas, reducing coupling and preserving MIMO performance in compact arrays.

Integrated cooling channels between stacked circuit carriers raise T/R channel density while limiting antenna depth and improving heat dissipation.

Integrated heat sinks and conductive adhesive layers cool stacked antenna amplifiers, enabling tighter pitch and stable high-frequency transmission.

Switchable excitation modes let a phased array alternate between narrow and wider beams for radar search, floodlight illumination, and SAR coverage.

Combiner cards group radiating elements onto common feed lines, shrinking phased array feed networks and easing replacement.

A layered multiplexer layout eases dense array antenna wiring and signal conduction between the antenna and beamforming module.

A nested transmit-receive antenna layout enlarges virtual array aperture for better angular resolution without degrading wide-angle detection.

Modular RF tiles switch between independent subsets and a coherent phased array to balance throughput, range, directivity, and power use.

Pluggable signal processing and spliced antenna bays let one antenna adapt to different frequency-band scenarios while easing maintenance.

Probe-fed intermediate patches in a via-backed cavity cut feed radiation and improve cross-polarization in wideband dual-polarized arrays.

Electronic phased-array steering replaces motorized terahertz optics, speeding image acquisition while reducing size, weight, and power use.
