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.

LINE新功能悄上線 台、日用戶看傻眼:完全不想用了
LINE 是最多台灣人使用的通訊軟體,近日有女網友發現LINE悄悄上線「AI 自動生成訊息」功能,輸入框旁多了一個「AI」按鈕,點選後可即時生成回覆句子,引發討論,部分網友更新想體驗新功能,實際操作卻未見選項出現,但在日本已有多數用戶已可使用該功能,紛紛發文抱怨,台灣網友也直呼「更不想用LINE了」。
原PO今(9)日在Threads發文分享,表示LINE已推出AI自動生成訊息功能,讓她驚訝直呼「我居然現在才發現」。
從女網友上傳的截圖可見,當朋友傳訊息給她時,她準備回覆卻意外發現輸入框旁多了一個「AI」按鈕,點選後系統會依照好友傳送的訊息內容,即時生成4個句子,語氣和真人回覆相似,還搭配表情符,但原PO說,該功能一天只能使用3次,超過就得付費解鎖。
