  • Patent number: 4051477
    Abstract: A radio frequency antenna structure is disclosed wherein a raised pedestal portion of the ground plane surface is provided and above which pedestal portion a microstrip radiator is disposed. The microstrip radiator is thus disposed on a pedestal at a predetermined distance above the base ground plane to produce mirror image or apparent radiating aperture(s) therebelow. The combined radiation pattern from the real radiating aperture(s) and the mirrored image(s) thereof produces an increase in radiation power at low pointing angles located near the ground plane, thus producing a wider radiation beam without sacrificing radiation efficiency. This form of raised pedestal microstrip radiator is especially useful in phased arrays where it is desired to steer the beam of the array to angles near the ground plane itself.

  • Patent number: 4043523
    Abstract: Apparatus for providing extreme pitch trim configurations for aircraft capable of flying at low-speeds, and particularly aircraft having blown primary lift-producing surfaces. The apparatus includes a movable horizontal stabilizer to provide pitch trim and an elevator pivotally attached to the horizontal stabilizer to provide transient pitch control. Control of the elevator movement is provided by a control tube extending from a horn attached to the elevator to a bell crank member attached to the horizontal stabilizer. The bell crank is also connected to a push tube movably attached to the airframe and arranged to be aligned with the pivot axis of the horizontal stabilizer in the neutral position. Thus, the horizontal stabilizer may be pivoted around its mounting axis to provide substantial pitch trim while concurrently maintaining the range and symmetry of elevator movement.

  • Patent number: 4038662
    Abstract: A broadband antenna in the form of a multiple element interlaced dipole array is mounted on a thin elongated strip of dielectric material which is mechanically flexible, light weight and electrically small. Each dipole has a first tapered radiator section with an inductive loading section electrically connected to one end of the tapered radiator section. A capacitive end-loading section is connected to the inductive loading section. Second tapered radiator sections are joined to one another by a second inductive loading section. The inductive loading sections increase the effective electrical length of the first and second tapered radiators, respectively. A UHF gap filling conductor is connected to each of the dipoles to suppress grating lobes at the high-frequency end of the frequency spectrum received by the antenna.

  • Patent number: 4014016
    Abstract: A sightless indicating system and method is disclosed that is useful as an indicating device for diverse equipment, including equipment such as an electronic calculator, and is particularly useful by a blind person. When utilized as a part of an electronic calculator, a standard calculator keyboard is modified to include a sign key and an output key so that an operator can initiate output indications and determine the sign of such indications in addition to initiating the customary numerical and function inputs. The customary numerical and function inputs are processed in conventional manner except that the calculator output is converted to a sightless indicating form, such as audible signals indicative of output.

  • Patent number: 3971032
    Abstract: A conformal microstrip antenna structure formed by a plurality of separated spaced-apart electrically conducting elements on a dielectric substrate overlying a ground plane. The innermost edges of the separated conducting elements define two sets of two intersecting radiators which are fed by microstrip transmission circuits disposed within the space between the separated conducting elements to individually feed the various radiators and/or segments thereof from the common feed point. The dimensions of the conducting elements also determine the resonant frequency of the radiators and their relative phases such that dual frequency operation as well as circular and/or elliptical polarization of the received/transmitted electromagnetic radiation can be conveniently achieved.

  • Patent number: 3938161
    Abstract: A microstrip antenna structure is provided wherein a plurality of relatively narrow elements, resonant in their longer dimensions, are organized into two staggered or offset sets of interleaved elements with each set being fed from opposite sides of the structure through a corporate microstrip feed line from a common feed point. The aligned radiating ends of the two offset sets of elements simulate four line sources of radiation. The preferred embodiment produces an efficient end-fire radiation pattern from this relatively compact structure which may, in turn, constitute an individual end-fire radiator in a larger array structure.
