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

吃加工紅肉易失智 哈佛研究揭2替代品:大降2成風險

人人都怕老來會失智。腎臟科醫師王介立表示,研究發現,每天吃超過4分之1份、約23克的加工紅肉,例如培根、熱狗、香腸,與增加13%的失智及14%的認知衰退風險有關,若改以堅果或豆類取代1份紅肉,可使失智風險下降19%,認知衰退風險降低21%,並使大腦老化速度變慢約1.4年。
王介立在臉書粉專PO文指出,這項研究是由麻州醫院、哈佛公共衛生學院及Broad Institute等機構共同進行,這個月發表在《Neurology》期刊,由醫療專業人員對近13萬4000 人,進行飲食問卷(2~4年更新一次)、失智診斷、客觀認知測試、主觀認知衰退(SCD)自我評估,追蹤時間達43年。研究結果發現多吃紅肉,尤其是加工紅肉,與失智風險和認知衰退有關。
王介立指出,上述研究發現,每天吃超過1份(3盎司,約相當於93克、1塊肥皂大小)未加工紅肉,與16%的認知功能下降的風險上升有關;每天吃超過4分之1份(約相當於23克)加工紅肉,例如培根、熱狗、香腸,與增加13%的失智風險及14% 的認知衰退風險上升有關。
