生意盎然的春季來臨，來自東京的手工餅乾名店Aunt Stella詩特莉帶來繽紛春夏系列新品，首度與台灣知名插畫藝術家「Eszter Chen 陳純虹」聯名合作，推出以「畫框」為概念研發的全新造型禮盒，融合Eszter畫作中代表性的鮮明色彩與可愛動物元素，呈現告別冬日的歡欣喜悅。獨家設計的禮盒上蓋不僅可掛於牆上裝飾，九宮格內盒亦可留做飾品收納，為居家環境增添質感氛圍。

迎來春季之餘除了為生活換上新擺飾，也適合與閨蜜和另一半相約走出戶外，一同在草地上共享悠閒的午後暖陽野餐時光。今年春天，Aunt Stella詩特莉特別將年初廣受歡迎、迅速售罄的

全新升級設計，換上符合季節的柔美色彩包裝限量回歸，以經典手工餅乾及磅蛋糕搭配品牌特製玫瑰金餐具組，打造顏值與風味兼具的野餐美食選擇。

隨著疫情影響邁入第三年，過往延宕的婚禮熱潮也逐漸湧現。一向致力於提供獨特喜餅選擇的Aunt Stella詩特莉，特別於春夏系列的各款新品設計中蘊藏祝福巧思：畫框禮盒可將藝術家畫作客製化替換為新人照片，藤編造型及其他季節款則以浪漫花語為主軸延伸設計，滿載新人迎接美好未來的期待。

今年春夏，Aunt Stella詩特莉新品禮盒將帶來煥然一新的風貌；除了以畫框九宮格設計重新定義禮盒的多功能再利用，好評回歸的質感藤編造型系列亦不僅是夢幻野餐季的好夥伴，選做婚約喜餅禮盒更可向親朋好友分享最別出心裁的喜悅與祝福。

HORN ANTENNA CALIBRATION

1.) The dual-polarization (HQ-Series or HR-Series) antenna has an electronic switch that may simultaneously test horizontal and vertical or +-45deg polarization, as well as a couple that can test circular polarization.
2.) The dual-polarized antenna (HQ-Series or HR-Series) is mounted on the chamber's bracket or wall (this is the way to test the antenna)
3.) If the dual-polarized antenna is being used for something else and calibration is needed, we can certainly assist.
4.)Single-polarized antennas (HA-Series, HB-Series, and other antennas) are commonly used to replace the antenna method's calibration antenna. When HA calibration is utilized, the calibration site is lost (patch loss uses a network analyzer) Enter the antenna's gain (minus the gain of the antenna, equal to the address of the object under test, return to zero)

5.) There is only one technique to compute antenna gain. The path loss patch loss subtracts the antenna's gain and substitutes the antenna under test to obtain the antenna's gain.
6.) Rotate the object under test after calculating the antenna route loss and gain calibration numbers (requires a rotating table, 2D test)
7.) If you want to read the horizontal and vertical antenna patterns at the same time with a dual-polarized antenna, an RF electronic switch, and a 3D rotating table, you can get the antenna pattern of the antenna (3D testing requires the use of HA-Series calibration twice, Horizontal and vertical or +-45deg),

8.) Antennas can be tested in a variety of methods (if you have any questions, you can provide simple photos or hand-drawn pictures, and we can assist you in the test plan)

9.) To ensure that the test value of the antenna is in compliance with international standards, all Horn products developed by FT-RF have passed internal calibration and testing in collaboration with external national research institutions, as well as third-party confirmation tests.

10.)In most ISO systems, we will demand external calibration of our test items every three years and internal self-calibration every other year. You can use the network with a set of HA-Series antennas. Calculate the path's loss using an analyzer (but usually at least three antennas can be used for internal correction, we can do internal correction by replacing the three antennas in turn)

11.)The antenna can be shipped back to Taiwan for calibration once every three years (you must know the shipping cost and the economic impact), or you can purchase a fresh set of calibrated antennas (we will calibrate the antenna internally).

11.)The antenna can be sent back to Taiwan for calibration once every three years (you must know the cost of shipping and the economic impact), or you can purchase a new set of calibrated antennas (we will calibrate the antenna internally or It is externally corrected and then sent to the customer)

12.) Antenna calibration is mostly done by an external calibration unit that must bear the ISO17025 and TAF logos.

13.)For the difference comparison test, you can use internally calibrated antennas, self-calibration, and ISO17025 antennas; this approach is frequently used in the ISO9001 series.

Double-Ridged Horn Antenna
Sort by:Select
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.
