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。
