氣候任性．臺灣韌性 ”降雨篇”特展
圖說:本世紀中的你幾歲？是學生、上班族或已退休的你，有可能面臨什 麼樣的降雨情境？科工館，演給你看！(科工館提供)The horn antenna has a distinctive design that is enlarged towards the end. Horn antennas typically feature a directional radiation pattern with a high antenna gain of 10-20 dBi, some antennas have a higher gain such as the standard horn antenna up to 25 dBi. Horn antennas feature a low VSWR and a wide impedance bandwidth.
Double Ridged Horn Antennas are very popular from 200 MHz frequency to higher frequencies up to 40GHz. We have recently extended the usage frequency of this antenna up to 60 GHz.
This antenna's operating frequency has recently been increased to 60 GHz. The research process for the product line is still ongoing but is planned to be completed this year. To receive the most recent price and technical information on the new product, please contact us for more information.
Double Ridged Horn Antennas are suitable for both transmitting and receiving purposes, with applications:
- - Antenna measurement
- - Communication systems
- - Satellite tracking systems
- - Radar Detection System
- - Surveillance System
- - Electromagnetic Compatibility Testing (EMC test)
Recommended Accessories
- - Antenna Tripod: easy and fast-changing position. 100% stable after installing.
- - SMA Cable: High-quality special SMA cable

SUMMARY TABLE OF DOUBLE-RIDGED HORN ANTENNA (HA-SERIES)
2020年至2021年的百年大旱，南臺灣甚至超過 600 天沒有降下大雨（降雨量大於 200 毫米），這樣的現象可能給民眾帶來深刻的印象。去（2023）年「氣候任性．臺灣韌性」特展的「序曲篇」，向民眾介紹了氣候變遷對人類所帶來的影響。展出期間科工館對觀眾的問卷調查顯示，71.6%的觀眾認知到氣候變遷威脅的風險，包括高溫、海平面上升、以及降雨不均等現象；其中對於「降雨不均」則有 71%的觀眾表示非常擔心。2023 年 Google 搜尋的關鍵字，第 1 名是「颱風」，也部分呼應了這一項調查結果。 科工館為回應社會大眾的憂慮，今年特展以「降雨篇」為主題，聚焦於氣候變遷下的臺灣降雨。透過圖文並茂與互動展示方式，說明何以臺灣是全世界總降雨量前幾名的國家，卻有時要面對缺水危機；臺灣的降雨不均可以從時間與空間來瞭解；看到稻農應用臺灣科學資訊，找出水稻關鍵生長時期階段的調適方法，以面對灌溉用水短缺的難題。在本世紀中臺灣的降雨，可能會如何影響我們的生活？不管那時的你是在北部、南部、你是學生、上班族，還是已退休，科工館運 用互動投影方式，預演給你看。 從知道「降雨不均的事實」到「找出種水稻的調適方案」以及「推估未來可能的降雨情境」，這些事實與推估，預告人們及早因應、省思與做出一些改變。
圖說:科學家是怎麼推估出世紀中、世紀末的氣候情境的呢？(科工館提供)
