Omni-directional orthogonally-polarized antenna system for MIMO applications are disclosed herein. An example antenna system comprises two arrays of horizontally polarized radiating elements, and two arrays of vertically polarized radiating elements, each array having roughly 180-degree radiation pattern, disposed about a central axis in a common horizontal plane, arrays of common polarization separated by 180-degrees. Also, the example antenna system includes at least one printed circuit board having a saw tooth pattern, wherein uniform coverage in both vertical and horizontal polarization over 360 degrees is provided using beamforming and polarization diversity.

Orthogonally-polarized antenna system and device for MIMO applications

Omni-directional orthogonally-polarized antenna system for MIMO applications are disclosed herein. An example antenna system can have two arrays of horizontally polarized radiating elements, and two arrays of vertically polarized radiating elements, each array having roughly 180-degree radiation pattern, disposed about a central axis in a common horizontal plane, arrays of common polarization separated by 180-degrees, such that MIMO processing of signals to the arrays of common polarization results in a radiation pattern that is substantially constant over 360-degrees in azimuth.

Omni-directional orthogonally-polarized antenna system for MIMO applications

Sector antenna arrays and methods of use that provide high main-lobe gain and high side-lobe rejection over a wide range of operating frequencies are provided herein. The example sector antennas provide these outstanding performance and reliability features due to (1) a cross-section profile for the ground plane, (2) a corporate feed for the linear array of patch antennas, and (3) an optimized sub-assembly of parasitic elements for high bandwidth operation with low return-loss.

Mobile robot for object detection

Waterproof apparatus for cables and cable interfaces are provided herein. An exemplary apparatus includes a coupler body that includes a first end configured to releaseably couple with a connector bulkhead and a second end having an opening that is sized to receive a sealing gland, a cavity for receiving the sealing gland, the sealing gland comprising an outer peripheral surface configured to sealingly engage with an inner surface of the cavity, the sealing gland comprising an aperture that is configured to receive a cable.

Waterproof apparatus for pre-terminated cables

Higher isolation solutions for printed circuit board mounted antenna and waveguide interfaces are provided herein. An example waveguide mounted onto a dielectric substrate can enclose around a periphery of an antenna and contain radiation produced by the antenna along a path that is coaxial with a centerline of the waveguide. The waveguide can have a first portion having a first cross sectional area that is substantially polygonal that transitions to a second cross sectional area that is substantially conical. A shape of the radiation produced by the antenna is altered by the first portion as the radiation propagates through the first portion. A second portion includes an elongated tubular member coupled with the first portion.

Higher signal isolation solutions for printed circuit board mounted antenna and waveguide interface

Higher isolation solutions for printed circuit board mounted antenna and waveguide interfaces are provided herein. An example device includes any of a dielectric substrate or transmission line, an antenna mounted onto the dielectric substrate, and an elongated waveguide mounted onto the dielectric substrate so as to enclose around a periphery of the antenna and contain radiation produced by the antenna along a path that is coaxial with a centerline of the waveguide, the elongated waveguide having a first cross sectional area and a second cross sectional area, and the first cross sectional area differs from the second cross sectional area.

Enclosures for radios, parabolic dish antennas, and side lobe shields are provided herein. A dish antenna includes a parabolic circular reflector bounded by a side lobe shield that extends along a longitudinal axis of the dish antenna in a forward direction forming a front cavity, and a sidewall that extends along the longitudinal axis of the dish antenna in a rearward direction forming a rear cavity.
