Abstract: In some examples, a dual polarity antenna includes a dual polarity radiator. The dual polarity radiator includes a first radiator having a first polarity and a second radiator having a second polarity orthogonal to the first polarity. The dual polarity antenna further includes an ancillary radiator. The dual polarity antenna further includes a feeding network for feeding a radio-frequency (RF) signal to both the first radiator and the ancillary radiator, driving the first radiator to radiate a wave having a first polarisation, causing radiation of a spurious wave having a polarisation orthogonal to the first polarisation, and driving the ancillary radiator to radiate a wave that cancels the spurious wave at least partly.

Abstract: An antenna device comprising an antenna array for transmitting a signal. The antenna array includes a plurality of radiating elements with each radiating element configured to radiate the signal with a predetermined phase. The antenna device further including another radiating element that is not part of the antenna array. The phase of the signal for each radiating element of the antenna array is controlled such that the signals radiated by the radiating elements of the array interfere destructively at at least part of the other radiating element.

Abstract: An antenna has a plurality of first radiating elements configured to radiate in a first frequency band and a plurality of second radiating elements configured to radiate in a second frequency band. The second frequency band at least partially overlaps the first frequency band. The first radiating elements are arranged along the longitudinal direction of the antenna in a first column, and the second radiating elements are arranged along the longitudinal direction of the antenna in a second column. The second column is separated from the first column along a lateral direction of the antenna. Further, feed points of each first radiating element are separated from feed points of each second radiating element along a bore sight direction of the antenna.

Abstract: The present disclosure relates to antenna devices and arrays of antenna devices. One example antenna device includes a first radiator configured to radiate a first electromagnetic signal, a second radiator configured to radiate a second electromagnetic signal, and a joint feeding network including a first 180-degree coupler and a second 180-degree coupler arranged in sequence. The first 180-degree coupler receives first input signal and second input signal, and the second 180-degree coupler provides first output signal to the first radiator and second output signal to the second radiator. In the joint feeding network, a first path connects the first 180-degree coupler to the second 180-degree coupler including a first phase shifter. A second path connects the first 180-degree coupler to the second 180-degree coupler including a second phase shifter and an attenuator.

Abstract: An antenna device. The antenna device includes a first radiating structure that operates at a first frequency band. A second radiating structure operates at a second frequency band. The second radiating structure includes a radiating loop formed along a closed line, wherein the radiating loop is made as a coil extending along the closed line and is electrically invisible at the first frequency band. The second radiating structure operates at the second frequency band that does not affect the performance of the first radiating structure that operate at the first frequency band even when both radiating structures are placed in the vicinity of each other.
