1. A thin, flexible, conformal package for a telemetry system for sensing and transmitting data relative to a device under test, thickness of said entire package being less than one-eighth inch and being flexibly conformable to a curved surface, said package comprising:

  • an essentially planar, flexible microstrip patch printed circuit antennaa very thin copper ground plane for said antenna, said antenna being insulatedly spaced from and adhered to said ground plane by an adhesive dielectric coating;

    a telemetering circuit intended when energized for supplying RF signals to said antenna for transmission to a remote location, said telemetering circuit including sensors, data acquisition components, a controller, and RF transmitter integrated into an essentially planar printed circuit, the upper and lower planar surfaces of said circuit being insulated with a thin film of dielectric material;

    a plurality of sensors, said sensors and said telemetering circuit being integrated onto a planar, printed, integrated circuit layer;

    a thin, flat battery adhered to said layer;

    a metallic ground plane between said layer and said battery;

    dielectric spacers between said ground plane and said layer;

    an adhesive on said battery for adhering said system to a device to be tested; and

    a peelable plastic sheet protecting the adhesive on said battery prior to adhering said battery to said device.
