ANTENNA PATTERN MATCHING AND MOUNTING
A technique for improving wireless communication characteristics involving matching transmitter antenna patterns to receiver antenna patterns. In a specific implementation, the transmitter antenna pattern adapts to changing parameters, such as when a smartphone is initially held in a first orientation and is later held in a second orientation. Because the transmitter antenna patterns match the receiver antenna patterns, signal quality between stations improves. In some implementations, antennas are organized and mounted to maximize spatial diversity to cause peak gains in different directions.
1 . An antenna apparatus, comprising:
an antenna mounting structure;
a plurality of antenna devices circularly arranged on the antenna mounting structure with a clearance from each other, the plurality of antenna devices including a first subplurality of antenna devices and a second subplurality of antenna devices arranged in an interleaved manner,
the first subplurality of antenna devices having a first polarization and not having polarizations orthogonal to the first polarization, and the second subplurality of antenna devices having a second polarization different from the first polarization and not having polarizations orthogonal to the second polarization.
