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.

醫師施冠偉在個人粉專發文表示，睪丸的主要功能在製造精子和分泌睪固酮。而睪固酮為最主要的男性荷爾蒙，對於男性的體毛、聲音、肌肉力量和性慾等都很重要。

施冠偉進一步提到，男性15～35歲是睪丸癌好發的高危險族群，因此，透過定時的自行檢查，有助於盡早發現睪丸異常狀況。建議可於淋浴時進行，溫水能使陰囊放鬆，更容易觸摸到是否有硬塊存在。
