    Abstract: A beam forming network system includes a first beam forming network having first and second ports, in which each of the first ports is operatively coupled to an antenna element; and a second beam forming network including third and fourth ports, in which each of the third ports is operatively coupled to one of the second ports using at least one of a phase shifter, attenuator, power divider, and/or hybrid coupler. A method of beam forming includes coupling each of the first ports associated with a first beam forming network operatively to one antenna element, and coupling each of the third ports associated with a second beam forming network operatively to one of the second ports associated with the first beam forming network using at least one of a phase shifter, attenuator, power divider, and/or hybrid coupler.

    Abstract: An antenna array system provides simultaneous 360° coverage and includes Butler matrix beam forming networks connected to an antenna array, which includes narrow and/or broadband elements, and multiple transmitters, receivers, or transceivers to allow for 360° transmission and/or reception. The antenna array system can provide multiple beams, such as without limitation 8 or 16 beams, which can vary in beam crossing and/or overlap to provide simultaneous 360° coverage. An antenna array system includes a plurality of antenna elements configured in an array, a first Butler matrix operatively coupled to the plurality of antenna elements, and a second Butler matrix operatively coupled to the first Butler matrix. A method of providing simultaneous 360° coverage includes configuring a plurality of antenna elements in an array, coupling a first Butler matrix operatively to the plurality of antenna elements, and coupling a second Butler matrix operatively to the first Butler matrix.

    Abstract: An antenna array includes a plurality of antenna elements coupled in a common area and extending radially outward from the common area. At least one of the plurality of antenna elements includes a first antenna portion and a second antenna portion arranged in a configuration such that a gap is formed between the first antenna portion and the second antenna portion. The gap includes first spacing associated with a first operating frequency and a first operating wavelength, and a second spacing associated with a second operating frequency and a second operating wavelength. A proportion of the first spacing to the first wavelength is substantially equal to a proportion of the second spacing to the second wavelength, thereby providing a constant beamwidth over an operating frequency band. A method of arranging a plurality of antenna elements in an antenna array is also disclosed.

    Abstract: Expression of recombinant polysaccharide degrading enzymes in plants is described. In one embodiment, expression of the enzyme is preferentially directed to the seed of the plant. Expression may also be preferentially targeted to specific locations within the plant cell. Expression of cellulases in corn is shown. The result is the capacity to produce polysaccharide degrading enzymes in plants at commercially acceptable levels in a reliable manner. Methods of using same in production of ethanol is also described, including use of the plant-produced enzymes in the ethanol production process.

    Abstract: A method of controlling germination of seed is provided in which a nucleic acid encoding a protein which causes inhibition of germination is transformed into a plant, operably linked with a promoter that expresses during germination. The protein is one in which a restoring substance can be applied to the seed and restores germination. Also provided is an amylase germination preferred promoter.

    Abstract: Embodiments of the present invention include a patch antenna having a patch element, a ground plane, a feedline, and an electromagnetic shield. The patch element transmitting and/or receives electromagnetic signals. The ground plane is spaced at a specified distance from the patch element. The feedline guides the electromagnetic signal and extends through an opening in the ground plane and to the patch element. The feedline is electrically coupled to the patch element to guide an electromagnetic signal to or from the patch element. The electromagnetic shield extends, at least partially, between the ground plane and the patch element and is electrically coupled to the ground plane. The electromagnetic shield is configured to control an impedance associated with the feedline between the ground plane and the patch element.
