Log Periodic Antenna (LPDA)對兩岸局勢樂觀 馬國首相安華：與俄烏、以哈衝突不同
馬來西亞首相安華（Anwar Ibrahim）24日在東京的日本記者俱樂部的記者會就台海緊張局勢加劇發表看法：「我樂觀地認為，除了軍事活動增加外，不會發生不必要的挑釁或戰鬥。」
解放軍東部戰區自23日起，舉行為期2天的「聯合利劍—2024A」環台軍演。據日媒《時事通信社》報導，安華表示，「這不是俄羅斯和烏克蘭，也不是以色列和加薩走廊。」他預測，兩岸衝突升級的可能性很低。
安華還表示，如果美中或兩岸之間的緊張局勢升級，將影響整個區域，他希望緊張局勢能夠以「和平友好的方式」得到解決。

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.
