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.

廉航新招？擬推超便宜「半站立座位」網友怒：根本奴隸船
為壓低機票價格，廉價航空可能將推出一項極具爭議的新措施，可能會變得更便宜，但也更擁擠，義大利的Aviointeriors公司推出了一種新型座椅，可以讓乘客採半站立的姿勢，能增加飛機載客量20%。雖然還沒有航空公司確認會使用這種設計，但它已經在社群媒體上引起了不少討論，有網友笑稱根本「奴隸船」。
每日郵報（Daily Mail）報導，根據擁有280萬粉絲的Instagram帳號 @entrepreneurshipquote爆料，這種半站立式設計的座位，最快可能在2026年投入使用。
這種新型座位由義大利航空內裝製造商 Aviointeriors 所研發，設計讓乘客以傾斜角度倚靠，而非完全坐下，此外，Skyrider 2.0重量比一般經濟艙座位輕50%，零件數量也較少，有助於降低維修成本。該公司更將其稱為「低票價與乘客體驗的新前沿」。不過截至目前為止，Aviointeriors沒有正式做出評論，也沒有任何航空公司證實將採用這項新座位設計
