Antenna alignment using a temperature-dependent driver |
摘要 |
A system having a steerable antenna coupled to a temperature-dependent driver. The driver has a shape-memory element fabricated using a shape-memory alloy (SMA) and having the ability to change its shape as a function of temperature. The element is adapted to steer the antenna to improve signal reception and is controlled by a control circuit, which resistively heats the element while using the strength of the electrical signal generated by the antenna in response to a received radio-frequency signal as a feedback signal. The temperature of the element is adjusted to optimize the signal strength. Systems of the invention may enable customer-performed antenna alignment and are relatively simple and inexpensive to implement.
