Abstract
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.
Claims4
A method of establishing a wireless connection between a base station and a mobile device, comprising:
- scanning a service beam through a plurality of scan angles, the service beam having a plurality of gain lobes, wherein the plurality of gain lobes move in unison;
- transmitting a unique scan index with each scan angle, the scan index corresponding to the scan angle;
- receiving a feedback from the mobile device, the feedback indicating a first index corresponding to a highest quality received scan angle;
- and
- establishing a mobile device-specific beam having a scan angle corresponding to the first index.
