Log Periodic Antenna (LPDA)
記者: 劉佳昌 台南報導
「孝順」與「行善」是這世上不能等的兩件事,農曆春節將至,成泰交通工程行今年透過學甲警分局社區警政機制,於113年2月3日共同舉辦「寒冬送暖 幸福過好年」活動,學甲警分局轉介轄內弱勢家庭154戶,並由成泰交通工程公司董事長林宗盛準備棉被、白米、罐頭、衛生紙等民生物資一同關懷慰問,同時進行婦幼宣導,另外林董事長再提供46份關懷物資給學甲警分局,讓勤區員警執行勤務發現需要救助民眾,能立即給予關懷救助。
學甲警分局長廖水池表示,結合社會資源關懷弱勢家庭,貫徹警政工作「視民如親」基本理念,期盼這些生活上的弱勢族群情況,能讓大家發現並予以關注,激發更多社會各界善心人士共同參與,在這個社會中注入多一點暖流。

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.
