First Claim
Patent Images
1. A method of controlling a mobile device comprising a radio frequency (RF) front end coupled to multiple antenna arrays, the method comprising:
- monitoring a first metric associated with RF signals that are communicated between the mobile device and a second device using a first array of antennas that is aligned with and next to a first area on a surface of the mobile device, wherein the first area is not shielded against RF interference (RFI);
monitoring a second metric associated with RF signals that are communicated between the mobile device and the second device using a second array of antennas that is aligned with and next to a second area on a surface of the mobile device, wherein the second area is not shielded against RFI; and
comparing the first and second metrics to select one of the first and second arrays for subsequent communication of RF signals between the mobile device and the second device.

Abstract
An antenna array can be mounted on a flexible substrate and connected by a flexible interconnect to an integrated circuit such as a radio frequency front end. The antenna array can be mounted in a device housing that includes radio frequency interference (RFI) shielding. The antenna array is aligned with and next to an area of the housing that is not shielded against RFI.
