Abstract

A multiband antenna structure having an open rectangular box shape is arraged to provide identical electrical lengths for all of its radiating elements notwithstanding that the physical dimensions ofportions 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 anoffset 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 serpentineshape, by having a radiating element follow a chicane, by incorporating a reflector of a 5G array, or by employing capacitive coupling.

Description

technical field [0001] The present disclosure relates to antennas, and more particularly, to the addition of a new type of antenna array to be used to provide wireless services using a space already used by existing antenna arrays to provide different wireless services. Background technique [0002] Obtaining new sites to place the antennas necessary to provide wireless service has become nearly impossible in most dense urban areas, especially for wireless services that require new types of antennas. Furthermore, the addition of new antennas supporting new frequency bands can lead to very lengthy, painful and expensive negotiations with the venue owner. As a result, the deployment of active antenna systems (AAS), a key enabler of so-called "fifth generation (5G)" wireless services, will likely be a major challenge for mobile network operators. In view of the foregoing, it is desirable to find a way of adding new antennas to already crowded venues, especially rooftops. Con...
