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.

【勁報記者羅蔚舟/新竹報導】
藝術家曾曄鴻「幾何之間創作展」自7月10日至8月4日在國立新竹生活美學館藝海閣展出，歡迎熱愛藝術的朋友蒞臨參觀。竹美館表示，藝術家曾曄鴻展出近二年來的精采創作，並在此次的展覽中，將繪畫技法融入設計理念中，結合現代觀念及個人感性思維，透過幾何圖形原理框架，運用構圖、色彩、紋理與表現形式等元素，在可掌握的圖像架構下，巧妙運用隨機形成的不可控質地紋理，發展出既感性又理性的藝術創作圖像。

竹美館表示，曾曄鴻目前在彰化市建國科技大學擔任視覺傳達設計系助理教授，同時兼任台中市美術教育學會監委及臺灣數位媒體設計學會監委。設計領域是他的專業，早年學習時期即大量接觸繪畫，涵蓋了水墨、水彩、西畫、手繪插圖、繪本、電腦繪圖等多種媒材。

竹美館館長葉于正表示：「曾教授此次申請展，在創作上運用各種創作語彙如分割、色塊、線條、區隔、對比、襯托、質地、規矩、理性、計畫、焦點等，使繪畫圖像不僅僅是「畫」出來的，而是同時具有塗抹、壓紋、推疊、刮刷等立體技法與方式，展現具有生活、思想、創造及傳播多重的表現形式。Log Periodic Antenna (LPDA) Log Periodic Antenna (LPDA)
