想要守護眼睛健康，飲食的選擇很重要。對此，營養師李婉萍分享護眼營養3關鍵，包括葉黃素、抗氧化劑，以及硝酸鹽，都能從許多天然食材中獲取。其中她提到，維生素C是天然的抗氧化劑，能降低白內障發生風險，像是芭樂、奇異果、草莓等，都是很好的食物來源；而葉黃素屬於脂溶性營養素，建議飯後30分鐘內服用為佳。

李婉萍於個人粉專發文介紹護眼3關鍵營養素。首先就是很多民眾熟知的葉黃素，她指出，一般綠葉蔬菜和黃色系蔬果，像是南瓜、玉米、香吉士、酪梨、奇異果、柳丁，以及菠菜、芥菜、地瓜葉等，都是補充它的好來源，特別是後面3款蔬菜的含量更是豐富。

此外，若是要是想透過保健食品來補充葉黃素，李婉萍說，由於葉黃素屬脂溶性營養素，建議於三餐飯後30分鐘內服用為佳，讓油脂幫助身體更好地吸收。

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.
