蘋果史上最便宜的5G iPhone ，第三代 iPhone SE 在今(11日）晚九點官網開放預購，3/18正式開賣，不過新iPhone SE 也有2大優點與2大缺點。

首先在缺點上就是螢幕尺寸小，僅有4.7吋，對於目前大多都是6吋以上的手機螢幕來說，轉換到iPhone SE 可能就要習慣畫面變小，眼睛比較吃力的狀況。但這同時也是優點，就是具備更好的手握感，對於手小的人可以一手掌握沒問題，並且有果粉非常喜歡的Touch ID 。

第二個缺點是續航力表現，由於新iPhone SE 硬體規格主要來自於2017年推出的 iPhone 8，不過以目前的設備性能來看，是不太符合目前消費者使用習慣，雖然蘋果有表示這次續航力有提升，但以第二代iPhone SE 來看，續航力約只有同時期的 iPhone 11 一半，所以第三代即便續航力有提升，但還是很難跟市面上旗艦手機相比。

不過iPhone SE 最大的優點就是價格便宜，除了處理器為 A15晶片，與 iPhone 13 同級，又支援 5G，是目前所有iPhone 中，最平價的一款手機，售價為 13,900 元起。

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.
