本文來自: https://n.yam.com/Article/20231008609986The 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.

【記者李祖東/高雄報導】今天由臺灣福德正神全國聯合總會舉辦的公益路跑活動，鄉親啊，你們有來參加嗎？土地公交代的任務，為今年度的陸巡文化祭熱身，土地公的神轎帶領大家跑全程！
林岱樺在天色微亮時，也來到林園東林福德廟位選手們加油打氣！
辛苦這幾天辛勤練跑的四駕，林園跑起來！
