熬夜害失智風險暴增 醫揭3招可補救
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

立法院進行總預算案表決，立委們挑燈夜戰，事實上，每個人都有熬夜的經驗。基因醫師張家銘表示，長期熬夜會使大腦難以清除代謝廢物，讓罹患阿茲海默症等失智症風險倍增，也會造成思考速度變慢，判斷力下降等傷害，建議民眾若無法避免熬夜，仍應抽空閉目養神，期間多喝水與吃抗氧化食物，熬夜後務必補眠，以讓大腦恢復能量。
台北榮總遺傳優生科主任張家銘在臉書「基因醫師張家銘」PO文指出，進入睡眠時，大腦會啟動糖淋巴系統（glymphatic system）。這套系統透過腦脊髓液的流動，清除神經元間隙中累積的代謝廢物，例如β-澱粉樣蛋白和τ蛋白。這些物質若堆積過多，會影響神經訊號傳遞，還可能與阿茲海默症等神經退化性疾病的發展有關。
張家銘指出，熬夜時上述清潔系統幾乎停擺，大腦無法清理廢物的結果，會讓神經訊號的傳遞效率降低，思考速度變慢，判斷力下降，甚至記憶力模糊。對需要在複雜政策中迅速抓住重點的人來說，這是一個巨大的挑戰。
