Collapsable Antennas Means TRIZ Cases

A deployable antenna expands from a compact carrier to increase effective surface area.

A multi-static radar system selects spatial data channels to enable effective volume visualization.

A rotary connector uses a spring in a groove to maintain continuous metal contact between rotating and fixed portions for EMI shielding.

Rotating hinge ribs extend the reflector perimeter to increase aperture area while maintaining a simple fixed inner section.

A collapsible log periodic dipole antenna uses a flexible rope frame to pivot radiating elements between storage and operational states.

Switchable antenna elements on a common reflector core adapt frequency bands without increasing manufacturing complexity or inventory costs.

Modular concrete ballast stabilizes a telescopic mast, enabling rapid height adjustment to overcome environmental obstructions.

Segmenting the reflector into nested flat panels resolves the contradiction between high directed gain and compact stowability in portable satellite terminals.

A flexible antenna assembly uses a bendable structure and overmolded protection sections to create a weatherproof seal.

Pivoting support arms fold the frame for compact shipping while tubular members reduce wind loading on the structure.

Bistable tapes transition flexible elements into a reflectarray, reducing part count and stowed volume while maintaining high-gain performance.

A mounting device with pivotally coupled support legs and a biasing element propels the legs outward to engage a wall cavity surface.

Nested protective tube insulates fusible wire from corrosive media while simplifying assembly via insertion design.
