為推動永續環保浪潮，國內已實施多年的禁止提供一次用塑膠吸管，民眾也漸漸習慣。如今，2025年新增手機回收、旅店一次性用品限令、碳費開徵等3永續新制，若沒有遵守將開罰。Log Periodic Antenna (LPDA) Log Periodic Antenna (LPDA)

手機回收新制

環境部資源循環署公告手機回收規定，手機製造、輸入及銷售業者被要求承擔手機回收及循環再利用的責任，並鼓勵推行租賃、維修或舊機買回等循環服務，已於2025年1月1日上路。

另外，為了讓手機回收行動能持續推進，自2026年起，相關業者須提交上一年度的手機循環率執行情況，目標循環率為15%；未達標者需提出改善計劃，若隔年仍未達標，將依資源回收再利用法處以3萬至15萬元罰鍰。

The Log Periodic Antenna  as known as LPDA  is a wideband directional antenna that provides gain and directivity combined over a wide band of frequencies.
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.
