Abstract:
1. A protective case for improving radio frequency (RF) signal quality for a mobile electronic device, the case comprising: a shell that encases at least a portion of the mobile electronic device; a case antenna attached to the shell; a two conductor transmission line attached to the shell and electrically interconnected to the case antenna; and a near-field coupling device attached to the shell and having a feed port electrically interconnected to the transmission line, the near-field coupling device configured to near-field couple to a native antenna of the encased mobile electronic device to capture an electromagnetic signal generated by the native antenna of the mobile electronic device, the near-field coupling device further configured to conduct the captured electromagnetic signal from the feed port of the near-field coupling device to the case antenna through the transmission line, wherein the mobile electronic device is configured to execute instructions to determine a location of the mobile electronic device, determine a preferred pointing direction for the case antenna based on information indicating known locations of communication base stations near the determined location, and indicate the preferred pointing direction on a display of the mobile electronic device.
