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)

隨著現代人長時間行走、站立於堅硬的平坦路面,足底疼痛、扁平足等問題日益增加。針對市面上種類繁多的鞋墊產品,衛生福利部桃園醫院復健部義肢輔具治療科物理治療師張立昌表示,了解足部結構及選擇合適的鞋墊是改善足部問題的關鍵。

張立昌解釋,足部並不是一塊平坦的骨頭,而是一個三維的弧形結構,通常稱為足弓。足弓具備吸震、減壓及推進行走的功能,當足弓出現異常,往往會導致各類足部疼痛。適當設計的足弓鞋墊能有效支撐足弓,幫助其正常發揮功能,並透過增加足底接觸面積,減少壓力集中,從而預防足底疼痛及腳底長繭。

他指出,人體足弓可分為內側足弓、外側足弓及橫足弓。好的足弓鞋墊需具備這三個足弓的支撐設計,並與足部結構完全吻合。若足弓位置不對,即便鞋墊標榜有足弓設計,穿在腳上也無法達到效果。因此,選擇鞋墊時,客製化設計尤為重要,因每個人的足弓高度、足長及足寬都存在差異,客製化鞋墊才能真正適合個人需求。
