ADAPTIVE ARRAY ANTENNA DEVICE AND ANTENNA CONTROL METHOD
First Claim
1. An adaptive array antenna device which wirelessly transmits content data to a partner device, said adaptive array antenna device comprising:
- a wireless transmission antenna unit configured to wirelessly transmit the content data to the partner device;
a wireless receiving antenna unit configured to receive control data indicating a receipt state of the content data of the partner device,a path information calculation unit configured to calculate transmission path information for specifying radiation pattern with which the content data can be wirelessly transmitted to the partner device, before an instruction to transmit the content data to the partner device is issued; and
a memory in which the transmission path information calculated by said path information calculation unit is stored,wherein said wireless transmission antenna unit is configured to start transmitting the content data to the partner device using the radiation pattern specified by the transmission path information stored in said memory, when the instruction to transmit the content data to the partner device is issued,and when the receipt state indicated by the control data received by said wireless receiving antenna unit falls below a predetermined threshold,said path information calculation unit is configured to calculate a new item of transmission path information that is different from the transmission path information stored in said memory, andsaid wireless transmission antenna unit is configured to resume transmission of the content data to the partner device using radiation pattern specified by the new item of the transmission path information calculated by said path information calculation unit.

Abstract
An adaptive array antenna device (120) includes: a wireless transmission antenna unit (121) which wirelessly transmits content data to q partner device; a path information calculation unit (123) which calculates transmission path information for specifying radiation pattern with which the content data can be wirelessly transmitted to the partner device, before an instruction to transmit the content data to the partner device is issued; and a memory (124) in which the transmission path information calculated by the path information calculation unit (123) is stored. The wireless transmission antenna unit (121) starts transmitting the content data to the partner device using the radiation pattern specified by the transmission path information stored in the memory (124), when the instruction to transmit the content data to the partner device is issued.
