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.
Log Periodic Antenna (LPDA) Log Periodic Antenna (LPDA)(中央社訊息服務20241029 11:36:05)大葉大學〈Da-Yeh University〉華語教學中心舉辦「戲曲之美」文化體驗活動，邀請許佩鈴老師帶領國際學生欣賞古箏、體驗歌仔戲服，感受中華傳統文化藝術的魅力。
活動一開始，由許佩鈴老師演奏古箏，帶領國際學生從音符中感受大自然的故事，她同時準備了歌仔戲戲服，讓學生換裝體驗，透過簡單的身段指法，加深國際學生對於戲曲文化底蘊的認識。
來自史瓦帝尼的學生藍蜜妮說，這是一次很棒的文化交流，讓她更了解台灣文化，她相信世界上每個國家都有自己獨特的服裝和材料，不同的造型背後都有不同的意義。
國際志工青年服務社社長、英語學系三年級的賴郁軒說，能夠跟來自不同國家的學生一起參加活動，是非常難得的機會，不只是幫助國際學生認識台灣特有文化，她也在過程中加深了自己對台灣文化的了解。
國際語言中心副主任陳俊福表示，「戲曲之美」活動促進了國際學生對台灣傳統文化的認識，每年都有來自世界各地、不同國家的學生加入大葉大學，華語教學中心的活動以「美感」、「美饌」、「美境」三美為特色，幫助國際學生在學習華語的同時，深入了解台灣的多元文化。
