Translucent flexible antenna film is only 130 to 185 microns thin
When integrated into the display, the antenna enables increased use of metal on the back cover of the handset. The mLUX flex antenna provides state-of-the-art RF performance and can be placed as far away as possible from the ground plane and the user’s hand, improving performance significantly. The device thickness can be reduced while achieving the same performance as standard flex antenna solutions. The antenna can be assembled to the display, covers, or a separate carrier with adhesive or, alternatively, it can be moulded between clear and opaque plastics.
When the antenna is placed near the display, smaller feeding elements can be used, reducing the total volume needed for the antenna. Total thickness of the flex is 130-185µm with a copper (Cu) thickness of 12µm. Non-pattern areas are filled with mesh to achieve a surface that is equally reflective throughout. The Cu mesh line-width is 12-20µm with 300µm pitch and the flex transmittance is typically around 80%. These RoHS compliant antennas are customized for each application and design and are available and ready for volume manufacture.
