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.

美俄18日在沙烏地阿拉伯就結束俄烏戰爭，進行長達4個半小時的會談，雖然烏克蘭與歐洲被排除在外，但美俄雙方在停戰談判上仍有進展，將繼續進行多次會談。川普表示他愈來愈有信心在2月底月前，有可能跟普丁直接會面。
俄羅斯在會談過程裡仍然強硬地重申其訴求，就是堅持無法忍受北約（NATO）同意讓烏克蘭加入為成員國。
川普在佛州棕櫚灘向媒體表示在停戰上，俄國是想要有所作為。至於烏國反應，川普並未理會其對於自身被排除在會談之外的憂慮，而是強調烏國將會提前加入談判。
