Now, we are focusing on automatic production lines and investing in automation equipment. In the future, we pledge to deliver the highest-quality product in the shortest possible period.

The horn antenna is a broadband passive device, shaped like a pyramid horn, referred to as a TEM antenna, which guides the beam of radio waves at a precise frequency. FT-RF Double Ridged Horn antennas have frequency capabilities ranging from 400MHz to 40GHz depending on type and style. These series are characterized by a huge frequency range and extremely high input powers. With increasing frequency, the gain rises to a maximum of 18 dBi. At higher frequencies, the increased gain compensates for the increasing cable losses.

The advantages of Horn antenna:

- Wide bandwidth: Because the horn antenna has no resonant parts, it can function over a wide range of frequencies.

- Easy waveguide interface: These antennas are very easy to interface to waveguide due to their shape, but they can also be designed with a transition so that a regular coaxial feeder can be used.

- Easy to make, simple design.

The horn is suitable for both transmitting and receiving purposes, especially suitable for EMC and immunity test measurements.

Recommended Accessories

- Antenna Tripod: easy and fast-changing polarisation. 100% stable handling

- SMA Cable: High-quality special SMA cable

▲獅子的出現，起初連老虎都感到畏懼。（示意圖／翻攝自Pixabay圖庫）

中國古代以天朝自居，鄰近的國家與地區，都有所謂的「進貢」等儀式，不過由於文化的差異，有些東西到了中國，反而有了不一樣的解釋方式。漢朝時期，「安息國」特使就曾進貢了一種猛獸，外貌被形容「似犬，頭毛極盛」，但丟到籠子裡卻讓萬獸之王老虎也「縮了」，這神奇的動物正是當今常見的猛獸「獅子」。

故事叫回顧到漢武帝時期，西域的「安息國」送來一頭獅子，但當時的中國社會，完全沒人看過這種動物，因此並不知道牠的威名。一開始，漢武帝看了看覺得沒什麼，就命人將獅子送進籠子裡「餵老虎」。

殊不知，獅子兇悍的外型，連當時被認為是最強猛獸的老虎，都不免感到畏懼，遲遲不敢靠近，更何況是吃了牠？《漢書》當時對於西域來的獅子，留下過一段記載「安息國王來貢，似犬，頭毛極盛，有長尾」。

此事傳回漢武帝耳裡，經過詢問這才知道，了解獅子的由來與特性，並對於牠令老虎也害怕一事，感到嘖嘖稱奇。為了避免造成危害，就將牠關在特殊的籠子裡，供人欣賞，成為一段歷史奇聞。
