蘋果(Apple )無預兆宣布推出新一代「AirTag」,具備更廣泛的尋找範圍,以及更響的揚聲器,讓定位、尋找物品變得更加容易;新款自1/26起供貨,售價與前一代相同,單件售價 NT$990,四件裝售價 NT$3,390,apple.com/tw 及 Apple Store app 提供免額外費的個人化鐫刻服務。
蘋果說明,新版 AirTag 採用 Apple 第二代超寬頻晶片,與 iPhone 17 全系列、iPhone Air、Apple Watch Ultra 3,以及 Apple Watch Series 11 所搭載的晶片相同,讓定位變得前所未有地容易。「精確尋找」功能可透過觸覺、視覺與音訊回饋,引導使用者找到物品,適用距離最遠比前一代長 50%。升級後的藍牙晶片也擴大了可定位物品的距離範圍。

Both Log-Periodic Antennas and Yagi antennas are high gain directional antennas. The main difference between these antennas is that Log-Periodic Antennas support wider frequency bandwidths and are physically much larger than Yagi antennas. The log-periodic dipole array typical VSWR is 2:1 and operates over a much wider bandwidth and will have a lower gain for an equivalent number of elements. With this level of performance, it is ideal for many applications, although a log-periodic antenna will be much larger than a Yagi of an equivalent gain.
