Multi-channel multi-sector smart antenna system
First Claim
1. An antenna system comprises:
- a flat substrate;
a first integrated antenna unit, including a first array of antennas spaced apart to accommodate a second array of antennas in an interlacing fashion along a first axis, mounted to at least a first bracket affixed to the substrate;
a second integrated antenna unit, including a first array of antennas spaced apart to accommodate a second array of antennas in an interlacing fashion along a second axis, mounted to at least a second bracket affixed to the substrate, each of the first and second integrated antenna units respectively adjusted around the first axis or the second axis with respect to the substrate such that main beam directions of the first and second integrated antenna units are formed with an angle towards the substrate, wherein the angle is less than 90 degrees, each of the antennas being substantially identical in size and structure.

Abstract
Techniques of designing a smart antenna system are described. An antenna system includes at least two integrated antenna units arranged with a predefined angular angle therebetween to form a desired antenna pattern without any significant nulls. According to one aspect of the techniques, at least two sets of antenna units are interlaced but polarized differently to form an integrated antenna unit. Each of the antenna units is formed with an array of antennas. The antennas in an array or the antenna units in an integrated antenna unit can be selectively energized to form a desired antenna pattern in accordance with a signal determined from radio frequency signals communicated between a device equipped with the antenna system and another device (e.g., a Wi-Fi router in communication with a mobile device), where the desired antenna pattern provides an optimized antenna pattern to facilitate seamless or QoS communication between the two devices.
