你能想像，一棟15層樓的辦公大樓，沒有一台冷暖氣，電力自給自足，還有專屬app推薦你哪個位置最舒服？

這棟世界最永續建築The Edge，就位在北歐的金融中心阿姆斯特丹，更被彭博盛讚為「世界最聰明建築」。整棟大樓零空調，僅以馬達推動的水循環調溫；用電來自外圍加裝的太陽能板，對環境友善又零負擔。

如今，世界最聰明建築即將再進化，就連37層大樓，都能用木材來蓋！繼2015年The Edge完工之後，致力於永續建築的建築設計事務所PLP建築，又將在鹿特丹蓋起名符其實的樹屋大樓Tree House，創下荷蘭木造建築高度新高。

而且樹屋大樓真的有樹！頂樓的3座玻璃溫室，種植豐富的植物。不只綠意盎然，還能吸收建築排放的二氧化碳。

The horn antenna is a broadband passive device, shaped like a pyramid horn, referred to as a TEM antenna, which guides the beam of radio waves at a precise frequency. FT-RF Double Ridged Horn antennas have frequency capabilities ranging from 400MHz to 40GHz depending on type and style. These series are characterized by a huge frequency range and extremely high input powers. With increasing frequency, the gain rises to a maximum of 18 dBi. At higher frequencies, the increased gain compensates for the increasing cable losses.

The advantages of Horn antenna:

- Wide bandwidth: Because the horn antenna has no resonant parts, it can function over a wide range of frequencies.

- Easy waveguide interface: These antennas are very easy to interface to waveguide due to their shape, but they can also be designed with a transition so that a regular coaxial feeder can be used.

- Easy to make, simple design.

The horn is suitable for both transmitting and receiving purposes, especially suitable for EMC and immunity test measurements.

Recommended Accessories

- 天線三腳架: easy and fast-changing polarisation. 100% stable handling

- SMA Cable: High-quality special SMA cable

木材作為最傳統的建材，早在18世紀就被主流淘汰；到了21世紀，技術革新與永續思潮，卻又讓木材回到先進住宅的舞台上。尤其全球超過40%的碳排，都與建築產業有關；作為最自然的建材，木材加工的環境汙染小，加上運送輕便，碳足跡只有混凝土、鋼筋的一半。

其實樹屋大樓並非PLP第一棟木造建築，他們在過去幾年持續與劍橋大學合作，研發出更防火、防震的木材。該公司資深合夥人巴克（Ron Bakker）表示，使用木材建造遠比其他材料，更容易達到碳中和甚至減少碳排。

因為木材不只比其他材料碳排低，種樹的過程，更能將既有的碳回收封存。建築師葛林（Michael Green）分析，一棟20層樓建築，用木材建造可回收封存碳排3,150噸，而鋼筋水泥反而還多排放1,215噸，兩者相差4,365噸。木材由於可預先在工廠進行加工，且易於運送，建造速度還快上20％到30%。

不只美國的木造建築，於2021年為止的兩年間成長50%；日本更拾起傳統的木造工藝，要用木材蓋起摩天大樓！

2041年將迎接創立350週年的住友林業 (SFC)，宣告將打造高350公尺、共計70層樓的木造摩天大樓Ｗ350，將於2024年開工。90%來自木材，不但耐震耐燃，完工後將為世界第一高的木造建築。

受俄烏戰爭、疫情影響，世界缺工缺料問題嚴重，影響持續多久仍未知。兼具美觀與永續意涵的木材，能夠加速建造、節省勞力，或將成為營建業的未來。
