Antenna isolation elements
First Claim
1. An antenna array, comprising:
- at least first and second antennas; and
an antenna isolation element formed from a loop of conductor that is configured to isolate the first and second antennas from each other, wherein the antenna isolation element is formed from a sheet of conductive material that extends around an axis to form the loop of conductor, wherein the loop of conductor has a gap, wherein the sheet of conductive material has a first dimension that spans the sheet of conductive material parallel to the axis and has a second dimension associated with a peripheral length of the sheet of conductive material around the axis, and wherein the first dimension is 1-10 cm and the second dimension is 1.5 to 3.5 cm.

Abstract
Electronic devices may be provided with antenna structures and antenna isolation element structures. An antenna array may be located within an electronic device. The antenna array may have multiple antennas and interposed antenna isolation element structures for isolating the antennas from each other. An antenna isolation element structure may have a dielectric carrier with a longitudinal axis. A sheet of conductive material may extend around the longitudinal axis to form a conductive loop structure. The loop structure in the antenna isolation element may have a gap that spans the sheet of conductive material parallel to the longitudinal axis. Electronic components may bridge the gap. Control circuitry may adjust the electronic components to tune the antenna isolation element.
