PS: This is the very minimum cable selection requirement. Performance could be more optimized if cable length is shorter or premium cable is adopted. 5. Recommended Assembly for WLAN Module

This is to prevent the module touching on the panel ground. ’ Giving at least 1-2mm gap or applying insulators (insulating tap) in between module & panel for better isolation. (please note: This gap or isolation is only necessary when there is noise inducing from the LCD panel) 6. Solution for Thermal Reduction and Improving Antenna Gain Adopting copper /aluminum foil or heat sink and then adhere it onto the top of combo module shielding case. The bigger the foil/heat sink, the better the thermal conduction. Please note that 1~2mm gap
WLAN 802.11bgn 1T1R and BT2.1 EDR combo slim module Application Note Combo slim Module Rev 1.0 Micro-Star International Co., Copyright 2009 Proprietary and Confidential 10the size of foil/heat sink should just fit properly onto the shielding case. Foil/ heat sink size larger than shielding area will impact the antenna performance. See below picture as a reference for correct cutting size. Copper foil is highly recommended as it will enhance antenna performance. 7. Recommended Placement for Combo Module’s Antennas. Leaving a gap between the combo module and NB housing ( the screw hole) for better antenna performance. 0.5mm GAP ( BT) 10mm GAP ( Wi-Fi)
WLAN 802.11bgn 1T1R and BT2.1 EDR combo slim module Application Note Combo slim Module Rev 1.0 Micro-Star International Co., Copyright 2009 Proprietary and Confidential 11For Wi-Fi side, 10mm gap is recommended. For Bluetooth side, 0.5mm gap is recommended. Note: please avoid any metal parts to cover, touch or surround with antenna. 8. Recommended The Size Of Copper /Aluminum Foil 9. Recommended The EMI Coating Area We suggest the area of EMI Coating must be within the length of Green line :100mm and the width between blue line A and B (from the end of panel to end of A side). Don't Coating exceed this area.
