Patent ID: 8581790

Claim:
A method, performed by one or more devices, the method comprising: tuning, by the one or more devices and based on a first Voltage Standing Wave Ratio (VSWR) measured for a first directional antenna, the first directional antenna for a particular VSWR, the first directional antenna being tuned for a first radiation pattern; tuning, by the one or more devices and based on a second VSWR measured for a second directional antenna, the second directional antenna for the particular VSWR, the second directional antenna being tuned for a second radiation pattern that is more narrow than the first radiation pattern; measuring, by the one or more devices, a combined radiation pattern of the first directional antenna and the second directional antenna; determining, by the one or more devices, whether the measured combined radiation pattern matches a particular radiation pattern; and when the measured combined radiation pattern does not match the particular radiation pattern: re-tuning, by the one or more devices, the first directional antenna for the particular VSWR; re-tuning, by the one or more devices, the second directional antenna for the particular VSWR; measuring, by the one or more devices, a second combined radiation pattern of the first directional antenna and the second directional antenna; determining, by the one or more devices, whether the second combined radiation pattern matches the particular radiation pattern; and repeating, by the one or more devices, the re-turning of the first directional antenna, the re-turning of the second directional antenna, the measuring, and the determining until a combined radiation pattern of the first directional antenna and the second directional antenna matches the particular radiation pattern.
