Patent number: 11682838Abstract: 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.Type: GrantFiled: June 29, 2018Date of Patent: June 20, 2023Inventors: Jerome Plet, Zied Charaabi, Thomas Julien, Jean-Pierre Harel

Patent number: 11611151Abstract: 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.Type: GrantFiled: June 29, 2018Date of Patent: March 21, 2023Assignee: NOKIA SHANGHAI BELL CO., LTD.Inventors: Jerome Plet, Zied Charaabi, Thomas Julien, Jean-Pierre Harel, Aurelien Hilary
