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. ![創作者 periodic 的頭像]()

2024台灣燈會安平燈區2月3日開展,環保局事前出動掃街車、清溝車及人力,加強周邊道路清潔及水溝清淤,開展期間天天都安排60人投入環境巡檢、清理及公廁維護工作,呼籲民眾落實垃圾分類,一同保持環境最佳狀態。
市長黃偉哲提醒市民朋友,2024臺灣燈會在台南舉辦,除了環保局全力動員投入環境清潔工作,更發包委外廠商負責垃圾打包分類,希望民眾一同維持燈會最佳賞燈環境。
環保局在安平燈會營運前即做足清潔準備,1月29日起動員掃街車清掃安平燈區主要道路安億路、慶平路等中央分隔島及路側區域,較狹窄及限高路段則由區隊掃街人員分區負責;為確保排水順暢,亦派遣清潔隊員加強清潔主要道路側溝,清除堵塞排水孔的垃圾和樹葉等雜物。
環保局長許仁澤表示,安平燈區起跑在即,清潔隊員全力投入周邊路段環境清理工作,包括路面清潔及水溝通暢等部分都加強清潔,希望在燈會營運期間給賞燈民眾一個友善環境。
環保局表示,開展期間,以早晚班制每天出動近60人投入展區清潔工作,假日增至70人加強環境清潔;針對廠區內7處流動廁所,也派員隨時待命,務必要保持環境品質至燈會結束。
