常聽到「喝咖啡會骨質疏鬆」的說法，讓許多人感到擔憂。對此，台北榮總遺傳優生科主任張家銘彙整多項研究後指出，飲用咖啡和茶不僅不會造成骨鬆，反而可能有助於降低骨折與骨鬆的風險；此外，若同時攝取咖啡和茶，其對骨骼健康的保護效果比單獨飲用其中一種更強。

醫師張家銘在個人粉專發文提到，在檢視2024～2025年的多項大型研究後，對於咖啡、茶與骨骼健康的關係有了全新理解。根據2024年來自英國生物樣本庫的一項研究，針對49萬名38～73歲的成人進行長達12.8年的追蹤，結果發現每天喝1～2杯咖啡者，骨鬆風險降低了10％；若再加上每天喝茶，保護效果更明顯，風險下降幅度可達32％。

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

不僅如此，張家銘說，根據2025年發表於《Frontiers in Nutrition》的一項統合分析研究，涵蓋全球56萬2838名受試者，也發現了類似結果，每天喝1杯以上咖啡者，骨質疏鬆風險降低21％，而每周喝茶超過 4次的人，風險降低25％。
