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]()

(觀傳媒中彰投新聞)【記者廖妙茜/台中報導】台中「張老師」中心今(18)日舉辦義務「張老師」授證及頒獎典禮,活動以「我善有您,愛無終止」為主題,邀請副市長黃國榮出席頒獎,包含台中市績優服務團隊獎及資深義務張老師榮譽退休獎。黃副市長表示,感謝「張老師」們陪伴無數人走過生命中每個低潮與失落的階段,用溫暖的語言,全年無休提供愛與關懷。
黃副市長表示,每位義務張老師都是市民心理健康的重要守護者,用行動及時間落實「我善有您,愛無終止」,作為生命守門人的第一線防護,一同守護市民朋友的心理健康。
台中「張老師」中心張麗莉主委表示,活動現場共149名義務「張老師」受聘,並表揚服務資深及績優義務「張老師」。榮譽退休獎2位得獎者年齡均達70歲、服務滿15年以上,持續努力不懈,用愛灌溉有需要的民眾;另「終身殊榮輔導服務獎」得主已累績服務40年,服務時數達8,106小時。

衛生局指出,張老師基金會和1980專線為市府的重要夥伴,提供台中市心理健康網絡重要資源。自民國101年開始,基金會長期協助市府辦理免費定點心理諮詢,今年已提供1,196心理健康服務人次,歷年累積服務則至少1萬7,077人次。此外,基金會也長期配合災難心理和相關講座及活動等,是非常重要的合作夥伴。
今日授證典禮,副市長黃國榮、台中「張老師」中心主任委員張麗莉、救國團總團部主任秘書羅健龍、台中市諮商心理師公會理事胡純閔及台中「張老師」中心各發展委員、諮詢委員均蒞臨現場。
