Disclosed is a multiband antenna having a plurality of low band radiators, a plurality of mid band radiators, and a plurality of high band radiators. The high band radiators are disposed in a column between two adjacent low band radiators. Each of the low band radiators has a plurality of inward dipole arms and a plurality of outward dipole arms, wherein the inward dipole arms and the outward dipole arms have a different structure. The inward dipole arm structure is designed to minimize interference and shading with the high band radiators. Each of the mid band radiators has a parasitic disk with a plurality of cloaking slots.

Multi-band antenna array face and radiator configuration for mitigating interference

Disclosed is a quasi-omnidirectional antenna having three array faces, wherein each of the three array faces has a radiator array having a plurality of radiator columns. Each of the corresponding radiator columns on the radiator arrays are coupled together to a single pair of antenna ports, one per polarization. This results in a service beam having three gain lobes that can be swept in unison in a scan. By scanning the service beam, the antenna may enable a high-gain connection to a mobile device, emulating a high gain omnidirectional antenna. Further disclosed is a variation having four array faces spaced 90 degrees apart, which offers additional performance benefits.
