5 GHz to 70 GHz Double Ridged Broadband Waveguide Horn Antenna, V-Female Connector (1.85mm)

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.

  • 5 GHz to 70 GHz Double Ridged Broadband Waveguide Horn Antenna, V-Female Connector (1.85mm)
  • EMC/ EMI test Antenna 

The antenna main body with the bracket using CNC precision manufacturing, and adopt a more weather resistant material aluminum material and the surface through the 6061 and 7071 Aluminum special handling to prevent oxidation.

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 application of horn antenna
- Antenna feeds for parabolic reflectors
- Radar systems with a short-range

The horn is suitable for both transmitting and receiving purposes. the product is 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

▲乾隆皇帝的風流韻事,最讓人感到好奇!(示意圖/翻攝自百度百科)

《延禧攻略》播出後熱度不減,讓清朝時期的乾隆皇帝成為關注焦點,尤其有關乾隆皇帝的風流韻事,最讓人感到好奇!曾有一位妃子,在乾隆帝65歲時,為乾隆帝生下一美麗公主,乾隆高興地不得了,還給了特別的賞賜,讓其它嬪妃羨慕不已!

這位妃子就是惇妃,本名為汪氏,是在乾隆年老之時才進宮的。此時的乾隆雖然已經到了垂暮之年,但是汪氏當時只有17歲,看到這樣的妙齡美女,乾隆帝春心蕩漾,並寵幸了此人;過了一段時日,惇妃竟然為皇帝產下了一個公主,此時的乾隆已經到了65歲的高齡,老來得女讓他十分高興。

汪氏生下的女兒,由於在公主中排行第10位,人們便將這位公主叫做十公主;在看到生下來的是個女孩子之後,乾隆便放心的將自己所有的寵愛都傾注到了這個孩子身上。假如汪氏生的是個男孩的話,恐怕乾隆就不會將自己的喜歡表現的這麼明顯,但因為女孩不會牽扯到皇位之爭。所以乾隆也不用因為擔心引起別人的猜疑而故意克制自己的喜歡。

話說乾隆一生之中,去過六次的南巡,因此見識過大江南北的各種事物。在其南巡之時,乾隆就發現南方的瓜果與北方大為不同,而且不乏許多美味的存在,其中就包括了黃瓜。作為一個很會享受的皇帝,乾隆想盡辦法也要在北方吃到這些美味的瓜果。後來就有人將菜種在溫泉旁邊,經過無數次的實驗,最終獲得了成功,並在冬天種出了十幾根黃瓜。

在北方冬天,黃瓜算是稀有品種,整個皇宮才結出了幾根黃瓜,而乾隆為了表達對汪氏的喜歡,便在一次宴會中當場賞了兩根給汪氏。這兩根黃瓜雖然在我們現在看來非常寒酸,但在那個時候,卻代表著來自乾隆的無上寵愛,後宮嬪妃都非常羨慕她。
