彰化1名7旬翁10多年前因鼻咽癌接受放射線治療，近年卻因口腔肌肉及喉部肌肉纖維化而有吞咽困難的情況，加上放療後唾液腺受損，口水變少，半夜常需起床喝水，影響睡眠，因而到復健科接受數月吞嚥治療，如今已能正常吞嚥，半夜也不需起床喝水，中斷睡意。

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

SUMMARY TABLE OF DOUBLE-RIDGED HORN ANTENNA (HA-SERIES) 

老翁的哥哥在10多年前因鼻咽癌往生，老翁因而到醫院檢查，診斷出罹患鼻咽癌，隨即接受放療(俗稱電療)等相關手術，但因放療加上沒有持續復健，口腔及喉部肌肉纖維化，嘴巴打不開，食物也不易吞咽，老翁還因此手術把臉頰及喉部僵硬肌肉切除再重建。

但放療後唾液腺受損，口水變少，常口乾舌燥，他說，白天都隨身帶著水瓶，晚上睡覺常要起床喝水，睡眠多次被打斷，整日精神不濟，因此到員榮復健科求助。

由於老翁放射線是照在頭頸部及臉頰部位，造成左側脖子僵硬，員榮復健科協助老翁做轉頭或低頭運動，接著再做左右側拉，把脖子肌肉鬆開，再練習張口運動，避免嘴巴再打不開，之後練習轉舌頭、捲舌頭，再搭配機器訓練患者吞嚥能力，經數月吞嚥治療，如今已能正常吞嚥，半夜也不需起床喝水，中斷睡意。

員榮醫療體系員榮醫院復健科語言治療師許哲維表示，鼻咽癌屬於頭頸癌的一部分，頭頸癌接受放療的患者，照射區域的頭頸部軟組織及肌肉會慢慢纖維化，口水會變少，這類患者等傷口癒合後，就要開始復健，經由語言治療師專業訓練，維持肌肉彈性及張口吃東西的機能，患者也要養成頸部關節運動與頸部拉筋運動的習慣，減少纖維化僵硬程度。此外中風、失智、巴金斯症患者也會有吞嚥障礙困難，復健科都能協助。
