阿茲海默症6大徵兆

醫師謝炳賢在個人粉專發文表示，阿茲海默症的症狀不單純只有記憶力衰退，還可能出現以下6大徵兆，若平常不會有這些狀況，結果突然就出現了，務必提高警覺：

1、語言能力減退 ：患者可能難以找到合適的詞彙表達意思，或說話內容變得重複且不連貫。與人溝通時，可能因理解能力降低而感到困惑。

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.
