  • Patent number: 8350771
    Abstract: A dual-band, dual-orthogonally-polarized antenna element includes a dielectric substrate having a conductor layer that includes a square ring slot and a shorted square ring, with each having a pair of orthogonal feed points. The shorted square ring is fed with coaxial probe feeds, while the square ring slot feeds striplines terminated in open-circuited stubs for coupling energy to each pair of orthogonal feed points. The first and second stripline feeds are not coplanar in order that each stub terminates past a center point of the element. The square ring slot operates as a high frequency band radiator and the shorted square ring operates as a low frequency band radiator, and both bands radiate substantially simultaneous dual-orthogonally-polarized modes. The modes can be any combination of dual-Circular Polarization (CP) and dual-Linear Polarization (LP), depending on the geometry of the radiators.

  • Patent number: 6264952
    Abstract: Vaccines against facultative intracellular pathogens are disclosed. A host is vaccinated with non-viable but metabolically active agents. The non-viable agents produce immunogenic components that elicit protective host immune responses, with minimal likelihood of host infection by the vaccine agent. Living agents, either attenuated or virulent, are exposed to a dose of gamma irradiation (or other strong mutagen) that is sufficient to limit or prevent the replication of the agents within the host, but that is insufficient to stop the metabolic activities of the agent. In vitro exposure of a microbial agent to the damaging effects of gamma irradiation or of another strong mutagen induces certain stress responses in the infectious agent. These stress responses are similar to the stress responses that the virulent agent would produce within the tissues of the host.
