ABSTRACT:
A log periodic VEE antenna particularly useful for space craft including a central mast and dipole antenna elements which are collapsible into a compact configuration for transportation purposes and which are deployable in spring-like fashion when released from their confinement. In one embodiment, the antenna elements themselves are semi-circular elements and confined in a bent position in a suitable container for transportation and which, when removed from the container, spring into deployed position. In another embodiment, the dipole elements are flexible wire with a spine member having a semi-circular spring member bent when the antenna is collapsed and which, when released from its confinement deploys the wire elements. The semi-circular elements besides having a deployment function also give rigidity to the antenna when deployed.
