Log Periodic Antenna

寵物中心／綜合報導

在電影以及動畫中，時常能看見巨大生物入侵的橋段，如果那個巨大生物恰好是喵星人呢？有日本網友在推特上分享一系列「貓咪入侵娃娃屋」的照片，視覺上貓咪變得超大隻，不過網友們還是很買帳，直說「太可愛了」。

日本網友森永タミー（@tammy_morinaga）在推特上分享一系列的「貓咪入侵娃娃屋」照，比如這張貓咪在房間內的照片，牠躺在床上雙眼緊閉，身旁還有芭比娃娃陪伴，雖然畫面看來有些違和，但是「貓＋芭比娃娃」的組合也讓網友少女心爆發。

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.
In terms of its specification, a typical log periodic antenna might provide between 3 and 6 dB gain over dipole for a bandwidth of 2:1 while retaining a VSWR level of better than 1.3:1. 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.

EMC/EMI pre-compliance test antenna.
Very high gain over the full frequency range.
 Meets latest EMC standards up to 7GHz.
Suitable even for immunity measurements

該網友後續還更新了新系列「貓咪破壞王」，畫面中可見都是貓咪入侵娃娃屋後的狀況，比如說這隻貓一臉慵懶的塞滿廚房，但是明顯快擠爆；還有貓咪直接把身體蜷縮在娃娃屋的客廳當中，周圍沙發與桌子四散；也有貓咪穿越娃娃屋的樓梯間，看到水晶燈忍不住就張嘴想嚐嚐，畫面像極外星人好奇地球人的房屋一樣。

這些「喵星人」自然的模樣實在太可愛，系列照分享出來後讓網友大呼「別睡在這裡啊」、「這不是你的房間」、「看起來微厭世」、「看起來也太擠」、「貓咪果然是外星人呢」、「感覺另一個世界線就是這樣」，還有人幫貓咪配厭世OS：「愚蠢的人類又在做些奇怪的事情了！」（徐薰懋整理）
