Log Periodic Antenna (LPDA) Log Periodic Antenna (LPDA)海運巨頭「 Seaspan」 子公司 『Seaspan Energy』，與氣候解決方案供應商 Anew Climate攜手合作，向北美西海岸的客戶提供『可再生液化天然氣』 (R-LNG)，為船東提供更永續的燃料選擇。

「 Seaspan」是一家總部位於太平洋西北地區的海洋運輸公司，為全球最大的集裝箱船租賃商，旗下業務涵蓋造船、鐵路渡輪、拖船和駁船運輸等。『Anew Climate』則是一家氣候解決方案公司，同時也是全球最大的可再生天然氣(RNG)營銷商之一，旨在提供創新技術減少碳足跡，

根據報導指出，「 Seaspan」和『Anew Climate』將共同推動航運業使用經過認證的低碳燃料，減少碳排。『Anew Climate』將供應符合國際海事組織(IMO)、歐盟FuelEU海事法規等標準的可再生天然氣，並為『Seaspan』提供國際永續發展與碳認證 (ISCC) 的預審服務。

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.
