Abstract: A direction finding antenna system includes a plurality of monopole elements disposed symmetrically around a center of a circular ground plane at the same radial distance from the center and a multimode combiner connected to the monopole elements to provide one or more mode outputs. A phase difference detector determines phase differences between selected ones of the mode outputs to provide azimuth bearing of a detected object. Typically, four or eight monopole elements are used. Placement of the inherently narrowband monopole elements in a bicone structure having a polarizer grid extends the useful bandwidth. Multiband coverage is achieved with a plurality of such antennas connected by a feed cable positioned on the polarizer grid to avoid interference.

Abstract: A method and apparatus for measuring temperature at different localized zones within a fluid medium, for example parts of the tops of fuel sub-assemblies in a reactor core, in which a continuous stress wave signal is transmitted from a remote location to targets at the zones, the frequency of the transmitted signal is progressively changed, waves reflected from the targets are received and multiplied with a reference signal, whose frequency changes at the same rate as the transmitted signal, to produce output signals wich are analyzed to derive values for the temperatures at points between the targets. A transmitter 10, target 12, receiver 14 are arranged so that oscillator 24 sweeps the transmitted signal and provides the reference signal to detector 28 which multiplies the received and reference signals and the beat frequency output signals from different targets are fed to a computer 38 for analysis.

Abstract: An interferometer spiral antennae array having a deformable cavity-less spacer which can be shaped to a nonplanar surface without distorting the alignment of the spiral antennae or increasing the difficulty of aligning Alignment is increased by mounting the spiral antennae the antennae. The accuracy of antennae on a stratum, separate from a ground plane by the deformable spacer. The spiral antennae are electrically connected to RF components on a stripline or microstrip feed/balun circuit board by integral finger-like extensions of the circuit, extending through the ground plane and the deformable spacer, thereby eliminating the need for connectors or cables.

Abstract: A generally paraboloidal shaped reflector with a coaxial feedline extending outwardly along the axis thereof and a disc antenna feed mounted in spaced relation from the reflector, said feed including a first disc forming a ground plane mounted coaxially on the feedline and a second disc forming a disc radiator mounted coaxially on the feedline. The center conductor of the coaxial feedline extends outwardly through the end thereof and back through an opening in the ground plane disc to a feedpoint on the disc radiator.

Abstract: A broadband antenna including a conductive disc parallel to and spaced from a ground plane with dielectric material therebetween, the disc including a first sector of approximately 270.degree. having a first diameter and the remaining sector having a second diameter different from the first so that the equivalent resonant structure of the antenna is essentially detuned to broaden the bandwidth thereof, and a cylindrical array of such antennas for providing a desired radiation pattern, generally omnidirectional.

Abstract: A stripline radiating element for use in a flat plate antenna array. The radiating element is comprised of a stripline sandwich including first and second stripline boards. A U-shaped slot is etched in the ground plane of the first stripline board and an open circuit transmission line is disposed between the two sandwiched boards for coupling energy to the slot. The inner dimensions of the slot form a strip transmission line with one end thereof, which is opposite the slot portion, being terminated in a short circuit which is formed by plated through holes between both ground planes of each individual stripline board. The length of the open circuited strip transmission line is adjusted to resonate with the slot susceptance and the reactance of the short circuited transmission line.

Abstract: Three spaced apart electrically conducting discs coaxially mounted with dielectric material therebetween, one outside disc forming a ground plane and the center disc being driven by a lead through the ground plane to form a first microstrip antenna resonant at a first frequency, and the center disc forming a ground plane for the other outside disc which if fed by a lead extending through both of the other discs on a plane of zero electrical field for the second plate and along a radius orthogonal with a radius through the first lead, to form a second microstrip antenna resonant at a second frequency.

Abstract: A stripline-to-two-conductor balun comprising series connected transverse electric magnetic mode (TEM) 90.degree. stripline couplers to transform an unbalanced stripline TEM field to a two wire TEM balanced field. The coupler sections of the balun comprises two overlay parallel conductors deposited on opposite sides of a dielectric layer and includes input stripline circuitry adapted to be connected to the input of one coupler section of the balun. The dielectric layer is disposed between and insulated from two parallel ground plane members. The output conductors are coupled through one ground plane member and are electrically connected respectively to one of an antiphase coupled arm of each series connected coupler section. The other coupled arm of each series connected coupler is terminated in a radio frequency (RF) short circuit, the direct coupled arm of the second coupler section is terminated in an open circuit.
