Abstract: A method of manufacturing an antenna using a radome (10) comprising a front portion (30) and a rear portion (20), the front and rear portions (20, (30) configured to define an interior cavity in which an antenna arrangement is received, the method comprising placing an antenna panel on an inside of one of the front and rear portions, and bringing the portions together, whereby the front portion (30) includes a peripheral channel region (31) configured to contain an adhesive sealant (60) and receive a peripheral edge (21) of the rear portion (20) that is partially submerged in the adhesive sealant (60) before it cures. Additional mechanical fastening clip engagement members (23; 33) are provided inside both the front and rear portions (20; 30) that engage with one another and mechanically secure the radome front and rear portions (20; 30) to each other, in addition to the adhesive joint provided by the adhesive sealant (60) once cured.

Abstract: Multiband multiple input multiple output (MIMO) dual polarised antenna assembly (100) comprising: dual polarised lower band antenna elements (10,20) mounted to ground plane (50) and located proximal to ground plane peripheral sides (50), the location of the lower band antenna elements (10, 20) defining lower band peripheral boundary; dual polarised upper band antenna elements (200, 210) mounted to ground plane (50) and nested within the lower band peripheral boundary; upper feeding network (130) connecting opposing pairs of lower band radiating elements (11, 12, 21, 22) of the dual polarised lower band antenna elements (10,20) and feeds the lower band antenna elements (11, 12, 21, 22), the upper feeding network (130) located within the lower band peripheral boundary; and lower feeding network (140) positioned below upper feeding network (130) and feeds the dual polarised upper band antenna elements (10, 20) via upper feeding network using pair of ultra-wideband duplexers (20A, 20B).

Abstract: A device obtains permission to use a Radio Frequency (RF) resource to transmit/receive data. The device comprises a transceiver and a processor that: controls the transceiver to communicate with a RF resource allocation system over the RF resource to determine whether the device can use the RF resource; while the transceiver communicates with the RF resource allocation system, repeatedly determines whether a cumulative use of the RF resource satisfies a condition until the processor determines that the cumulative use satisfies the condition or the device is permitted to use the RF resource; upon the processor determining that the cumulative use satisfies the condition, control the transceiver to not communicate with the RF resource allocation system over the RF resource for a period of time; and upon determining that the device is permitted to use the RF resource, controls the device to use the RF resource to transmit/receive the data.

Abstract: An antenna assembly for transmitting or receiving radio waves, comprising: at least one patch antenna element; a three-dimensional (3D) microstrip line feeding network configured to feed the at least one patch antenna element for operation in dual polarisation, the 3D microstrip line feeding network comprising an upper layer and a lower layer; and a ground plane; wherein a first air gap is provided between the at least one patch antenna element and the ground plane, a second air gap is provided between the upper layer of the 3D microstrip line feeding network and the ground plane, and a third air gap is provided between the lower layer of the 3D microstrip line feeding network and the ground plane.

Abstract: A radome (10) for housing an antenna (50), the radome (10) comprising a front portion (30); and a rear portion (20) configured to mate with the front portion (30); wherein the front portion (30) includes a peripheral channel region (31) configured to contain an adhesive sealant (60) and receive a peripheral edge (21) of the rear portion (20) that is partially submerged in the adhesive sealant (60) before it cures.

Abstract: A Distribution Point Unit (DPU) (10) having improved thermal management and electrical isolation, wherein a first mechanical fastener (200) engages with a first heat sink (50) and is configured to draw the first heat sink (50) towards the interior surface of a housing (31) in response to tightening of the first mechanical fastener (200) such that the first heat sink (50) becomes substantially flush with the interior surface of the housing (31); and wherein a first thermal pad (90) is electrically insulative to electrically isolate the first heat sink (50).
