Flexline wrap antenna for projectile

A method of assembling a projectile and a projectile circuitry assembly, the projectile comprising a chassis extending from a tail portion to a nose portion, the chassis defining a generally cylindrical wall of a main body portion and further defining an interior cavity within the projectile for containing one or more projectile components and further defining an antenna aperture slot extending axially through the cylindrical wall of the body portion exposing the interior cavity, and the projectile circuitry assembly comprising one or more circuit boards and a wrap antenna, the one or more circuit boards and the wrap antenna interconnected via an integrated flex-line to define a unitary device, the wrap antenna comprising one or more antenna elements that are defined on a flexible antenna substrate layer, wherein the method comprises:

• configuring the projectile circuitry assembly into a compact state such that the plurality of circuit boards are insertable into the interior cavity;
• disposing the antenna to extend through the antenna aperture slot;
• wrapping the antenna of the projectile circuitry assembly about the exterior of the chassis;
• and
• sealing the antenna aperture slot with a sealing material.
