A portable wireless communication device comprises a housing, a ground reference mass, a first antenna element, and a second antenna element. The first antenna element and the second antenna element are located at different sides of the housing. A radio-frequency (RF) port is electrically coupled to the first antenna element. An RF transmission line is located between the RF port and the second antenna element. The ground reference mass comprises a ground structure of the RF transmission line. An RF transceiver is electrically coupled to the first antenna element. The RF transceiver is further electrically coupled to the RF port to further electrically couple the RF transceiver to the second antenna element via the RF transmission line.

A modular communications systems includes an apparel item with a surface. Landing pads are positioned proximate to the surface with each landing pad uniquely positioned on the surface. Non-metallic antenna elements are each demountably, intermittingly, and conductively coupled to a unique landing pad; includes a non-metallic conductive composition; and a unique operational frequency compared to at least one antenna element. A hub is positioned on the surface and conductively coupled to each landing pad. Each communications device is demountably affixed to the surface; intermittingly, demountably, and conductively coupled to the hub; and includes a unique operational frequency. The hub intermittingly, demountably, and conductively couples each communications devices to a unique landing pad included in the plurality of landing pads.

A novel, interlocking, snap-fit connection between an antenna aperture and a ground plane layer that contains coaxial connectors is described herein. The snap-fit design provides a simple and solderless transition from the connectors to elements of the antenna aperture. This design facilitates easy assembly and disassembly, allowing parts to be removed, reinstalled and/or reused.

A vehicle, an antenna assembly of the vehicle, and a method of assembling the antenna is disclosed. The vehicle includes a housing having a passage formed therethrough. A circuit board is disposed within the housing. An antenna element is coupled to the circuit board and passes through the passage. A plug fills an annular volume of the passage between the antenna element and the housing.

A radio frequency antenna with a two-piece sealing ferrule. The antenna includes a center antenna and an outer tube surrounding the center antenna. A mounting nut surrounds and is slidable relative to the outer tube. An outer ferrule surrounds and is slidable relative to the outer tube. An inner ferrule that is separate from the outer ferrule surrounds and is fixed to the outer tube. A mating nut is secured to the mounting nut. The threading of the mounting nut and the mating nut together results in the wedging between the inner and outer ferrules which results in the exertion of a first compressive force by the inner ferrule against the outer tube for sealing the inner ferrule and the outer tube and the exertion of a second compressive force of the inner ferrule against the mating nut for sealing the inner ferrule and the mating nut.

The wearable antenna device includes an antenna partattached to a part of a garment including a body accommodation partthat accommodates a part of a body, and a functional element arranged in a position of the garment in such a way that at least a part of the functional element is opposed to the antenna part with the body accommodation part interposed therebetween. The functional element is another antenna part or an element that performs at least one of reflection, shielding, and absorption of radio waves

A communication device and a detachable antenna with dynamic antenna tuning is provided. The detachable antenna comprises: an electrically insulating base; a main antenna and a first antenna element, at the base, respectively operable at independent first and second given frequencies. The device further comprises: a memory associating the first and second given frequencies; an antenna port configured to detachably receive the base of the detachable antenna; a second antenna element, at the antenna port, operable to wirelessly interact with the first antenna element when the base of the detachable antenna is received at the antenna port; a circuit configured to detect wireless interactions between the second antenna element and the first antenna element; and a controller configured to: select the first given frequency using the second given frequency, as detected via the circuit; and, thereafter wirelessly communicate via the main antenna operated at the first given frequency.

A coupling assembly for a first device having a bayonet is provided. The coupling assembly includes a top plate, a bottom plate, and first fasteners securing the top and bottom plates to one another. The top plate having a slot along a connection axis, where the slot receives the bayonet. The bottom plate has a locking arm in axial alignment with the slot and a biasing arm in a region that is radially offset from the locking arm. The region of the bottom plate receives the bayonet, when in a locked position, with the locking arm preventing the bayonet, by interference with locking arm, from rotating about the connection axis back into alignment with the slot and with the biasing arm preventing the bayonet, by interference with biasing arm, from being withdrawn axially along the connection axis.

A modular feed system for axis symmetric reflector antennas includes an upper hat segment, a mid-section segment and a lower base segment, the upper hat and lower base segments being securable to respective opposing ends of the mid-section segment; wherein the length of the mid-section segment is selected in order to accommodate application of a particularly sized reflector antenna; and a mechanical mating mechanism including base slots for feed spring entry, corresponding carriage springs on the feed, and corresponding recessed spring capture locations; and wherein the carriage springs are sized and configured to pass through the corresponding base slots for feed spring entry as part of the initial mating of the feed to the base segment, and selective rotation thereof moves the corresponding carriage springs into corresponding recessed spring capture locations and causing a mechanically audible sound for indicating that the feed has locked into position.

A wireless repeater system, in accordance with embodiments, can include a first enclosure and a second enclosure. A repeater can be disposed in the first enclosure, and a donor antenna can be disposed in the second enclosure. The second enclosure can be selectively configurable to be coupled with the first enclosure as a unitary structure, or as a separate structure from the first enclosure. A reflector can be coupled to the second enclosure, be disposed in the second enclosure, be integral to the second enclosure, or be removably disposed between the first enclosure and the second enclosure when the second enclosure is coupled to the first enclosure as a unitary structure.
