摘要： An active passive antenna arrangement as made up of an array of 5G antennas interleaved with multiband antenna structures that may be low band (LB) passive antennas. The 5G antenna array may be a mMIMO active array. The LB antennas are formed using conductive elements on thin supporting sheets that fit within the space between the 5G antennas. The substrates, and hence the radiating elements of the LB antennas, may be arranged so as to generally appear to form four sides of a rectangular box with the top and bottom surfaces removed. Thus, the LB antennas may be thought of as having been “slipped in” amongst a preexisting array of 5G antennas. Each LB antenna may surround one or more of the 5G antennas and 5G antennas of the array may also be external to an LB antenna.

摘要： Apparatus forming a phase-shifter is described. The apparatus comprises a strip line and a moving dielectric part. The moving dielectric part surrounds the strip line and is adapted to move only along a longitudinal axis of the strip line. Within this apparatus the size of the area of the strip line surrounded by the moving dielectric part is modified when the moving dielectric part moves along the longitudinal axis.

摘要： A multiband antenna structure having an open rectangular box shape is arranged to provide identical electrical lengths for all of its radiating elements notwithstanding that the physical dimensions of portions of the multiband antenna may not be identical. Advantageously, such a multiband antenna may be interleaved with a 5G antenna array having unequal spacing between the 5G antennas or having an offset between at least one of the rows and the columns. This may be achieved by incorporating a dielectric material in at least one radiating element, by forming a radiating element with a serpentine shape, by having a radiating element follow a chicane, by incorporating a reflector of a 5G array, or by employing capacitive coupling.

摘要： An antenna comprising: a longitudinal support member for supporting components of the antenna and a method of assembling such an antenna is disclosed. The components supported by the longitudinal member comprise: at least one signal feed probe configured to capacitively supply a signal to a corresponding at least one radiating patch; the at least one radiating patch mounted to at least partially wraparound the longitudinal support member; and signal supply circuitry for supplying a signal to the at least one signal feed. The signal supply circuitry is mounted on an outer surface of the inner longitudinal support member; and the longitudinal support member is formed of a conductive material and forms a ground plane for the antenna.

摘要： A reconfigurable modular antenna system includes a first module comprising at least a first part of a first antenna system, and a second replaceable module comprising at least a second part of a first antenna system and a part of a second antenna system. An interconnect is disposed between the first module and the second replaceable module and couples the first part of the first antenna system to the second part of the first antenna system to form the first antenna system. The first antenna system is configured to operate in a first frequency band and the second antenna system is configured to operate in a second frequency band, different to the first frequency band.
