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
近年來孩子們的教科書越來越多元，題目有時甚至連家長都會被難倒而引起討論。不過就有家長在檢查作業時，發現女兒竟在答案格內畫了「4個鬼臉」，但題目曝光卻吸引大批網友笑喊：「我會給分」。
一位家長在臉書《爆廢公社公開版》上發文提到，女兒寫完作業後他開始檢查，結果發現一處答案格內竟畫了「4個鬼臉」。
而原PO檢查題目發現，該單元為「圈出錯別字」，而第一題的題目寫著「他用彩色筆書（畫）下金（全）班同學，圍一個園（圓）圈扮鬼儉（臉）的樣子」，本意是希望孩子能找出4個錯字，沒想到女兒卻誤解成要在答案欄畫下鬼臉，讓原PO只能苦笑「每次看作業我都會提醒自己記得呼吸！」
而超有創意的答案曝光後，立刻吸引5千多名網友按讚回應「看來您家閨女是走藝術的」、「我是老師一定給他對，創意無限，不要侷限」、「這樣的答案走在好前面」、「這種通常都是人才啊～不要抹滅她的想像力」。（編輯：潘毅）
