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.

Multiband antenna structure

The present application provides a multi-band antenna, comprising at least one low-band sub-antenna; and at least one high-band sub-antenna comprising at least one high-band dipole and a reflector; wherein the high-band dipole and/or the reflector are/is structured and positioned so that current induced in the high-band sub-antenna by the low-band sub-antenna is directed to reflector over an extended effective distance in proportion to wavelength of the low-band sub-antenna.

Multi-band antenna

A dual-polarization radiating element for a multiband antenna comprises a support with a high dielectric constant whose shape is roughly cylindrical, having an axis of revolution, at least a first and a second pair of dipoles printed on a first surface of the support, the dipoles of the first pair being roughly orthogonal to the dipoles of the second pair, and conductive lines, to feed each dipole, printed onto a second surface of the support. The support is placed on a flat reflector, with the cylindrical support's axis of revolution being perpendicular to the plane of the reflector.

Dual-polarization radiating element of a multiband antenna

The subject of this invention is a multiband antenna radiating element comprising a first pair of cross-polarization dipoles each of which comprises two collinear conducting arms, whereby the four conducting arms define a first radiating plane corresponding to a low frequency band. The radiating element also consists of at least a second pair of cross-polarization dipoles each of which comprises two collinear conducting arms, whereby the four conducting arms define a second radiating plan corresponding to a higher frequency band. The first and second radiating planes are parallel; the second radiating plane is positioned above the first from which it is electrically insulated and the surface of the first radiating plane covering the conducting arms of the first pair of dipoles is larger than the surface of the second radiating plane covering the conducting arms of the second pair of dipoles. The first radiating plane can be defined by a first pair of dual cross-polarization dipoles or one printed circuit dipole and the second radiating plane can be defined by a second pair of dipoles chosen from cross dipoles, butterfly dipoles and printed circuit dipoles.
