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.

今日張善政與出席貴賓一同恭請眾神明上轎，並恭送遶境隊伍出發，祝賀遶境圓滿順利。誠聖宮關公文化節自本（7）月11日至29日舉行，包括關聖帝君祝壽大典、神禧夜巡遶境、補秋運祈福法會、國中會考獎助學金頒獎、公益健走及園遊會等活動，傳承閩南在地文化。
民政局表示，蘆竹誠聖宮主祀關聖帝君，因位於桃園機場附近，故有「航空城武財神」 與「機捷守護神」之稱，保佑地方蓬勃發展；誠聖宮也熱心公益慈善，每年寒冬送暖捐贈物資予低收入戶、頒發獎助學金給在地優秀學生，並設置社區關懷據點造福市民。
