  • Patent number: 10236586
    Abstract: A corrugated feed horn for antenna has an oval pattern of corrugations, and a series of intermediate ridges spaced between adjacent corrugation ridges only in the regions of the slots near its major axis. The intermediate ridges provide a feed horn that is capable of producing a relatively uniform oval beam, and has enough corrugations per wavelength to guarantee little diffraction on the edges of the horn, thus resulting in an antenna with very low side lobes.

  • Patent number: 10224638
    Abstract: Disclosed is a lens antenna comprising a dielectric lens consisting of a collimating part and an extension part, and an antenna element. The extension part of the lens comprises a substantially flat surface crossed by the axis of the collimating part, and the antenna element is rigidly fixed on the surface. The antenna element is formed by a hollow waveguide and comprises a dielectric insert with one end thereof adjacent to said surface; the size of the radiating opening of the waveguide is determined by the predefined width of the main beam and by side lobe levels of the radiation pattern of the lens antenna. The technical result of the invention is an increase in realized gain value due to the use of a waveguide antenna element with a dielectric insert, which provides impedance matching in a wide frequency bandwidth. The present invention can be used in radio-relay point-to-point communication systems, e.g.

  • Patent number: 10199735
    Abstract: A TEM line to double-ridged waveguide launcher and horn antenna are disclosed. The launcher uses multiple probes or one or more wide-aspect probes across the ridge gap to minimize spreading inductance and a TEM combiner or matching taper to match the impedance of the probes over a broad bandwidth. The horn uses a power-law scaling of gap height relative to the other dimensions of the horn's taper in order to provide a monotonic decrease of cutoff frequencies in all high-order modes. Both of these techniques permit the implementation of ultra-wideband designs at high frequencies where fabrication tolerances are most difficult to meet.

The horn also has a substantially conical surface coupled to the first surface at a first slope discontinuity. The conical surface includes multiple surfaces each having a respective slope and coupled to adjacent surfaces by a respective plurality of slope discontinuities each having a respective diameter. The slopes and diameters are chosen to generate primarily TM1,m modes (m=1, 2, 3, etc.) in the high-frequency band and primarily higher order TE1,n modes (n=2, 3, etc.) in the low-frequency band such that the low frequency band and the high frequency band have approximately equal beam widths.

  • Patent number: 8947315
    Abstract: An antenna that resonates at each of at least operating two frequency bands includes a first LC parallel circuit having a first impedance between a feeding element and a feeding circuit, and a second LC parallel circuit having a second impedance between a parasitic element and ground. The feeding element and the parasitic element are configured such that multiple resonant frequencies are positioned between the two operating frequency bands in a case where the impedances of the first and second LC parallel circuits are set to 0, and the LC parallel circuits having the first and second impedances cause the multiple resonance frequencies to shift to an operating frequency band on the lower frequency side and to the higher frequency side, of the two operating frequency bands.

    Abstract: Apparatus is provided to allow the reception and/or transmission of data signals at two different frequency bands. The apparatus includes a waveguide (4) which has a first section (6) of larger cross sectional area for receiving and/or transmitting the lower frequency band signals, and a reducing section (8) which leads to a section with a reduced cross sectional area in comparison to the first section (6) and this allows the receipt of the higher frequency band signals. In one embodiment sections of the waveguide can be rotated to allow the apparatus to be adjusted to any particular orientation to suit the particular circular polarity trans mission type at the location at which the apparatus is provided at that time.

  • Patent number: 8933835
    Abstract: A two-channel directional antenna for use in a radar level gauge. The antenna comprises a partition wall dividing the antenna into a first partition for emitting an electromagnetic transmit signal, and a second partition for receiving an electromagnetic echo signal, the partition wall having an outer potion located downstream in a direction of radiation of the antenna. The partition wall comprises an electromagnetic de-coupling structure, which is arranged to reduce any leakage of electromagnetic energy from the transmit signal into the echo signal. The electromagnetic de-coupling structure according to the present invention ensures that the leakage of transmit signal into the received signal is reduced to a satisfactory level.

    Abstract: An antenna element employable singularly or in an array and configured for concurrent RF transmission and receipt on a plurality of frequencies concurrently. The element is formed of conductive material on a substrate by a pair of substantially identical horns extending in opposite directions to distal tips. A cavity formed between the horns narrows to a narrowest point prior to curving. The element is capable of wideband RF communication on any frequency between a low frequency defined by the distance between the distal tips to a highest frequency defined by the narrowest point of the cavity. The antenna is especially well adapted for portable devices such as smartphones where concurrent cellular, Wi-Fi, and bluetooth communications may be accomplished with a single element.

  • Patent number: 8847838
    Abstract: A microwave antenna suitable for monopulse radar applications is operable over a broad frequency band. The antenna uses a horn with two walls. Each wall includes two ridges that extend into an inner region of the horn near the horn's base and then taper into the wall surfaces. The horn is coupled to two ridged waveguide sections with the ridges of the waveguide sections matched to opposed pairs of the horn ridges. The antenna may be coupled to electronics via standard waveguides. In many embodiments, dimensions of the waveguides coupled to the horn are smaller (to provide a small array spacing) than dimensions of the standard waveguides with a tapered waveguide section providing a transition. In one embodiment, the antenna operates with frequencies from 5.25 to 10.5 GHz.
