  • Patent number: 10381707
    Abstract: Embodiments of the present disclosure use customizable waveguides that can be positioned next to each other in a structure that contains one single flange to provide a physical connection for the waveguides. In this fashion, many waveguides can be positioned within a small area to accommodate a tightly packed patch antenna array so that the waveguides can be positioned very close to the socket. As such, embodiments of the present disclosure allow more waveguides to be packed into a small area by providing a single structure that houses many waveguides and share only a single flange connection element that can be sized appropriately.

  • Patent number: 10290943
    Abstract: A dielectric loaded sleeve monopole antenna has a dielectric loading within the sleeve enables stable impedance in a dynamic operating environment. The use of a dielectric filling in the sleeve portion of the antenna enables tight control of the input impedance over frequency establishing stable broadband operation in challenging operating environments. The effective dielectric constant inside the sleeve of the antenna is designed to exhibit spatial variability. As a result, the sleeve essentially acts as an impedance transformer enhancing control over the input impedance to the antenna. The spatial variability in the dielectric filling may be realized as arrangements of single or multiple dielectric materials machined to synthesize the desired effective dielectric properties.

  • Patent number: 10236585
    Abstract: A dual band end fed dipole provides at least two distinct operating frequencies, e.g. 2.45 GHz and 5.5 GHz. Properties of the antenna include low cost to manufacture, e.g. ease of automation; minimal manual labor to manufacture, e.g. reliability; dual band operation; broad bandwidth; good feed line isolation; omnidirectional beam pattern; minimal vertical beam squint; small diameter; and high efficiency. Embodiments of the invention provide a dual band end fed dipole with a low band trap on the feed side that requires minimal manual labor to manufacture because the antenna is formed from a single flat sheet of metal and soldering is replaced with crimping. Minimal dielectric loading is also achieved.

  • Patent number: 9905940
    Abstract: Antenna arrays which can work simultaneously in various frequency bands thanks to the physical disposition of the elements which constitute them, and also the multiband behavior of some elements situated strategically in the array. The configuration of the array is described based on the juxtaposition or interleaving of various conventional mono-band arrays working in the different bands of interest. In those positions in which elements of different multiband arrays come together, a multiband antenna is employed which covers the different working frequency bands. The advantages with respect to the classic configuration of using one array for each frequency band are: saving in cost of the global radiating system and its installation (one array replaces several), and its size and visual and environmental impact are reduced in the case of base stations and repeater stations for communication systems.

  • Patent number: 9579152
    Abstract: Various high-strength microwave antenna assemblies are described herein. The microwave antenna has a radiating portion connected by a feedline to a power generating source, e.g., a generator. The antenna is a dipole antenna with the distal end of the radiating portion being tapered and terminating at a tip to allow for direct insertion into tissue. Antenna rigidity comes from placing distal and proximal radiating portions in a pre-stressed state, assembling them via threaded or overlapping joints, or fixedly attaching an inner conductor to the distal portion. The inner conductor is affixed to the distal portion by, e.g., welding, brazing, soldering, or by adhesives. A junction member made from a hard dielectric material, e.g., ceramic, can be placed between the two portions and can have uniform or non-uniform shapes to accommodate varying antenna designs. Electrical chokes may also be used to contain returning currents to the distal end of the antenna.

    Abstract: An antenna having a radiator comprising a conduct in a closed path driven by a plurality of microstrips connecting the radiator to a common, single feed and to a ground plane, with the radiator lying in a plane parallel to that of the ground plane. The radiator may be annular, with the feed located in its center. The relative location of the feed on the microstrips allows a lower input impedance to be leveraged to match a higher load impedance of the radiator. A single-ended input drives all points of the radiator substantially in phase.

  • Patent number: 8081130
    Abstract: A shortened multi-band antenna includes in-line dipoles, selected elements of which having shielded meanderline chokes to be able to switch from an extended dipole at the lower VHF frequencies to a shortened dipole for the UHF band. Additionally, the staggered asymmetric meanderline configuration permits overall size reduction, whereas antenna construction includes an intermediate fiberglass layer over which conductive foil is placed for tuning and for parasitic radiator purposes to improve the gain of the UHF dipole in the upper regions of the band at 450 megahertz. Additionally, at the low end of the 30 megahertz band a sleeve is positioned between the base of the lowest dipole element and ground, with the sleeve provided with two parallel RLC circuits tuned to different bands to improve VSWR at the low end of the VHF band and to eliminate unwanted nulls.
