摘要:
Method and system for tuning a tunable antenna uses a comparison between a signal response at two different tuning frequencies to determine how or if the tuning needs to be further adjusted. With the approach, the method and system arrive at a frequency shift that is centered about the desired antenna frequency, which point there is no net change in the signal response. In a further aspect, a frequency to which a tuned antenna is tuned is shifted to verify whether the antenna is still in tune. Modifications to minimize disturbance of the output received signal that would otherwise be caused by the frequency shifting are contemplated.
摘要(中):
用于调谐可调谐天线的方法和系统使用两个不同调谐频率处的信号响应之间的比较来确定如何或如果调谐需要进一步调整。 利用该方法,该方法和系统达到以期望的天线频率为中心的频移,该点在信号响应中没有净变化。 在另一方面,调谐调谐天线的频率被移动以验证天线是否仍然调谐。 考虑到最小化否则将由频移引起的输出接收信号的干扰的修改。
