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)粿粿跟范姜彥豐婚變風波持續延燒，之前范姜彥豐控訴粿粿與王子等友人在美國行後，回來整個人都變了還提出離婚，之後更是不回家，如今「鏡週刊」爆出粿粿這段分居時間，是由好友胡釋安提供住處，並且暗助粿粿和王子約會談不倫戀，對此，胡釋安的父親胡瓜做出回應。
據「三立新聞網」報導，對於胡釋安提供台北信義區住處，讓粿粿可以安心與范姜彥豐分居，胡瓜表示，自己沒有跟兒子住一起，所以並不知道此事，而之前他的YouTube頻道「下面一位」，曾邀請胡釋安、王子、粿粿等人來拍片玩交換禮物遊戲，當時影片中王子被問「要公開了嗎？」一旁的粿粿則突然尖叫。對此胡瓜也透露，自己與他們只有那次拍影片合作，私下其實並不認識，所以也不會知道這些事情。
據「鏡週刊」報導指出，9月時拍到粿粿進出位在信義區的住宅大樓，當時被疑是去小禎家，但遭到小禎否認，但其實胡釋安和小禎住上下樓，所以粿粿是住在胡釋安家，胡釋安和粿粿因為「全明星運動會」培養出好交情。
