Accumulation of debris, snow, ice, wildlife, insects, and other contaminants adversely affect antennas that are mounted outdoors. An antenna comprises a housing and a removeable inflatable cover. The housing may include one or more engagement features, such as a perimeter channel into which perimeter of an opening of the covering is retained. The covering may be selectively inflated to produce a motion in the covering that displaces accumulated contaminants and discourages further accumulation. Heaters may warm air inside the covering to facilitate melting of ice. Inflation of the covering may be responsive to environmental conditions. For example, during high wind conditions, the covering may be evacuated and retained in a collapsed configuration to reduce damage.

RADAR or other sensor assemblies/modules, particularly those for vehicles, along with related manufacturing/assembly methods. In some embodiments, the assembly may comprise a housing and a printed circuit board. The printed circuit board may comprise a first side and a second side opposite the first side and may further comprise one or more integrated circuits positioned on the first side of the printed circuit board. One or more antennas may be operably coupled with the integrated circuit. A flexible radome, such as a thermoplastic wrapper, may enclose the assembly and may provide the means for binding the printed circuit board to the housing.

An endfire antenna structure is disclosed that is for use on aerodynamic systems. The antenna structure includes a first layer of patterned metal, a second layer of patterned metal, and a stack of material layers that includes the first layer of patterned metal and the second layer of patterned metal. The first layer of patterned metal includes a plurality of parallel slots etched through the metal. The second layer of patterned metal includes a tapered radio frequency (RF) feedline having a narrow end coupled to an input/output (I/O) antenna connection. The second layer of patterned metal is aligned over the first layer of patterned metal such that the tapered RF feedline has a length that extends across the plurality of parallel slots. The stack of material layers is flexible such that the stack of material layers is configured to wrap at least partially around the fuselage of an aerodynamic system.

A radio frequency module includes submodules and a connection board that connects the submodule and the submodule. The submodule includes a module board and a first component arranged on the module board, the submodule includes a module board and a second component arranged on the module board, and the connection board is directly connected to the module boards and electrically connects the first component and the second component.

A recessed antenna that includes a recessed plane formed in a conductive surface. An antenna is disposed on the recessed plane. A cavity is formed beneath the recessed plane. A circuit board is disposed in the cavity. The circuit board is electrically coupled to the antenna. A cover is disposed over the antenna, the cover protecting the antenna from abrasion.

A radome assembly for an antenna, comprises: a mounting ring comprising an annular bonding surface; a layer of radome fabric or film bonded to the annular bonding surface and extending radially inwardly and radially outwardly of the bonding surface; and an annular enclosing element located radially outwardly of the bonding surface which encloses or covers at least a portion of the fabric of film radially outward of the annular bonding surface.

A distributed antenna includes a strip member extending in a strip-like shape including a dielectric body of a plate shape having a first surface that is one surface of the dielectric body and a second surface that is opposite to the first surface; a transmission line provided on the first surface, on the second surface, or between the first surface and the second surface; and a plurality of antenna elements electrically connected to the transmission line and disposed in a distributed manner on the first surface or on the second surface, or electrically connected to the transmission line and disposed in a distributed manner between the first surface and the second surface.

The present disclosure relates to a printed circuit board. The printed circuit board includes: a first substrate portion having a rigid region and a flexible region; and a second substrate portion disposed on the first substrate portion. The first substrate portion and the second substrate portion are disposed to be shifted such that portions of each of the first substrate portion and the second substrate portion overlap each other.

Invention relates to a radome casing and method for its manufacturing. The radome casing comprises walls (6, 11) of composite material which includes reinforcement fibers (8) and matrix resin (19) binding the fibers together. The walls include a radiation transmission window (11) through which the radiation of a radome antenna passes when the radome antenna (2) is mounted inside the radome casing (1). The amount of fibers in the radiation transmission window (11) is reduced to be less than 40-5% of the amount of fibers elsewhere in the casing walls (6). The reduction of reinforcement fibers in the radiation transmission window (11) reduces attenuation of the high frequency radiation.
