一名40多歲男子常以便當、宵夜當晚餐方式裹腹，日前因腹痛、腹脹就醫，竟發現1顆如桌球大的腫瘤塞住腸道，已是第3期大腸癌。醫師表示，男子飲食充斥著炸排骨、含糖飲料等高脂高糖食物，高脂食物易致腸道慢性發炎、形成腫瘤，含糖飲料則可能促進腫瘤生長，而男子確診前，早就出現排便習慣改變，他卻未能有所警覺，現已在進行化療。

收治病例的義大醫院一般醫學外科主任、大腸直腸外科主治醫師陳致一接受《中時新聞網》採訪時表示，上述男子是名工程師，工時長、壓力大，三餐多是買個排骨便當，或很晚下班時，買個炸物，配可樂、手搖飲解決，很少吃蔬果，這也是很多忙碌上班族的飲食習慣。

陳致一說，男子在發病前3個月，開始出現排便行為改變，原2、3天排便1次，變成1天大2、3次，每次只大一點點，大完還是很想大，肚子也常感覺悶脹，這已是大腸癌警訊，但他未在意，發病當天他與朋友聚餐，吃完後肚子脹痛到不行，又解不出便，因此到義大掛急診。

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.
