In RF antennas, everyone should be f紅吃amiliar with materials that d計要etermine whether the antenna ca笑火n work normally.

With the gradual and stead舞風y popularity of 5G, from the perspect她器ive of the antenna industry, the en匠但tire material industry chain around 5G通樹 has also ushered in new growth 輛城opportunities. The demand喝藍 for high-performance materials su樂物ch as PTFE, LCP, PPS, PPO, e子去tc. will also increase rapidly.哥聽

Among them, the LCP material known as舊制 "super engineering plastics" c為錯an be said to be one of the hott家音est materials in the 5G era.

Briefly introduce the LCP materials:

Liquid crystal polymer (Liquid Cry唱對stal Polyester) is composed o草鐘f a kind of rigid molecular chai明又n. Under certain conditions路請, there can be high molecula白呢r substances with the 會村fluidity of liquid and t上她he anisotropic state of crysta要村l physical propertie店師s. In short, althoug區報h it is solid, it has liquid properti飛很es and crystal properties.

Because of the excellent comprehensiv關海e properties of liquid crystal pol女爸ymer in thermal, electrical, mechan章機ical, and chemical aspects, it has bee水鄉n valued by various countries. I冷個ts products have been introduced int唱國o applications in various high-tech fi也林elds and are known as su高村per engineering plastics.

Compared with the tra匠藍ditional antenna soft音拿 board PI base material, the 2% el會們ectromagnetic loss is 畫事no less than 10 times smaller, which ca年西n effectively reduce the loss.

1. Clearance area

From mobile phone motherboards, chip我老s to other audio batteries and other西歌 mobile phone built-in h可鐘ardware, major mobile 答冷phone brands are constantl科北y compressing the use of built-in ha通市rdware in order to make th相白e mobile phone screen bigger. T人老hen the clearance area of ​​th用女e antenna becomes sma女暗ller.

LCP can make the antenna miniatur輛說ized, and the antenna radiat林睡or can be bent reasonably. It is 店低a way to reduce the size of能雨 the antenna in space. Whil房用e bending the antenna, 民河it can produce multi-mode reso間又nance characteristics. , Broadband is少問 helpful.

2. The LCP material can replace the 愛討original coaxial cable數雪 on the antenna for lar中房ge-capacity data transmi資作ssion. The thickness of 去民the flexible circuit using LCP m拿農aterial is only 0.2 mm! And has a th秒能ree-layer structure,購森 can carry several signal lines, can r車術eplace coaxial lines.

The LCP material soft boar笑工d has the same excellen長煙t transmission loss performance as睡視 the coaxial transmission line, an媽笑d lower cost.

The LCP film is used 輛樂to design an antenna 新他on it, and a coplanar wave作紙guide CPW is used to lead the si頻媽gnal to the chip end with low loss歌風, eliminating the need f但些or a thick coaxial cable. A兒習nd multiple RF lines can be led ou劇女t together.

Summarizing the advantages of the abov紙會e LCP material antenna,土好 the headroom area is increased, the L金校CP soft board does not need 內謝to be coaxial, the low ele喝就ctromagnetic loss ma從外terial, and the cost is lower, 書就this is LCP.
