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.

行程滿檔的五月天,重返大陸上海體育場舉辦6場「回到那一天」巡演,昨晚最終場邀請女團「i-dle」團員宋雨琦登台合體。主唱阿信在宋雨琦指導之下,搖身一變性感舞棍,讓她直讚非常好:「全能!立刻加入我們隊,做我們的舞蹈擔當。」
宋雨琦非常喜歡「後來的我們」一曲,應邀跟五月天合唱,提到歌詞雖然是悲傷的,卻帶給她充滿希望的感覺,興奮當嘉賓的她直喊:「站在台上就是這輩子最大的榮幸。」接著她說想看五月天跳舞,現場示範教學,更提醒要「性感的Wave」,阿信現學現賣小跳了一段「M.O.」,難得秀一手的他引發觀眾熱情尖叫。
其實五月天也很欣賞宋雨琦,阿信特別喜歡她的歌曲「Radio」,現場如願一起合唱。最後阿信出題要宋雨琦五選一,「如果五月天裡選一個給妳一個當大哥哥,妳會選誰」,宋雨琦不假思索地說:「可以貪心嗎?5個都要!」因為五月天缺一不可。Log Periodic Antenna (LPDA) Log Periodic Antenna (LPDA)
五月天下個月5日要前進大陸廣州,同樣也是6場演出,下個月27日則要回到台中洲際棒球場,舉辦「回到那一天」巡演陪粉絲迎向2026嶄新的一年。 五月天阿信(右)、宋雨琦即興共舞。圖/相信音樂提供
