In RF antennas, everyone should be familiar with©★₽‍ materials that determine whether π←€✔the antenna can work normally.

With the gradual and steady p&♦&÷opularity of 5G, from the perspective of the antΩ₩>enna industry, the entire​• material industry chain around 5↔✘G has also ushered in ne¥₽♥w growth opportuniti↓>es. The demand for hiλ↔gh-performance materials such as PTFE, LCP, PPS, ≤ >PPO, etc. will also increase rapidly.

Among them, the LCP material known as "super engi™¶®neering plastics" can be said to β be one of the hottes ↑t materials in the 5G era.

Briefly introduce the LCP materia>♥¥>ls:

Liquid crystal polymer (Liquid Crystal Polyes★±Ω→ter) is composed of a kind of r↓δigid molecular chain. Under certain conditions,∞↕÷ there can be high m ♣olecular substances with the fluidity of liquid★↑ and the anisotropic state of crystal phy£Ω ​sical properties. In short, althou✘♦↓gh it is solid, it has  β liquid properties and crystal properties.

Because of the excellent comprehensive p∑‍₹roperties of liquid crystal polymer in therma ♥l, electrical, mechanical, and chemical β₹™↑aspects, it has been valued by various countries•↓. Its products have been introduce§♣• d into applications i✘∑Ωn various high-tech fields and are known as ♦® super engineering plastics.

Compared with the traditional ¥♠‍antenna soft board PI base material, th∑εe 2% electromagnetic loss is no less than 10Ω<¶ times smaller, which can effecti"δvely reduce the loss.

1. Clearance area

From mobile phone motherboards, chip"¥₽s to other audio batterie™✘©s and other mobile phone built-in hardwar✘σe, major mobile phone brands are constφα ®antly compressing the use of built-in hardware ₩₩≤in order to make the mobile phone sc₽₽δ∞reen bigger. Then the clearα‍ance area of ​​the antenna becomes smaller.

LCP can make the antenna min≥©♦®iaturized, and the antenna radiator can' ♥  be bent reasonably. It is a way to  £≥reduce the size of the antenna in space. While be§&↔nding the antenna, it can produce multi-mode$ β§ resonance characteristics. , Broadb •∞and is helpful.

2. The LCP material can replace the •®™πoriginal coaxial cable on the antenna for$‌∏↔ large-capacity data transmission. The thickne≥ α>ss of the flexible cir☆→cuit using LCP material iλδ₩s only 0.2 mm! And has a three-laye∏♥r structure, can carry several signal linesΩ'₹, can replace coaxial linφσ₽es.

The LCP material soft board ha​↑£s the same excellent transmission loss performa¥λ nce as the coaxial traδ☆↔nsmission line, and lower cost.

The LCP film is used to desig₽ ∞n an antenna on it, and a coplanar waveguπ<ide CPW is used to l¶&‍ ead the signal to the chip e→​↑₩nd with low loss, elimin≠☆πating the need for a thick coaxial cable. An↕ ©§d multiple RF lines can be led out togeth©×₩ er.

Summarizing the advantages of the abov÷←e LCP material antenna, the he±¥adroom area is increased, the LCP σβ™↓soft board does not •&need to be coaxial, the low electromagnetic losγ☆s material, and the cost is lower, tπ☆his is LCP.
